Chocolate contains theobromine, a methylxanthine compound that dogs cannot metabolize effectively, making it toxic to them. Theobromine poisoning can cause vomiting, diarrhea, rapid heart rate, seizures, and even death in dogs. Options A and B describe effects that aren't the primary reason chocolate is bad for dogs, while obesity (D) is a secondary concern compared to acute toxicity.

Denmark's currency is the Krone (DKK), which has been its official currency since the 1870s. The other options belong to different countries: Peso is used by several Spanish-speaking countries, Koruna is Czech Republic's currency, and Kuna was Croatia's currency (now Euro).

Quarks are fundamental particles that cannot be broken down into smaller components - they are elementary constituents of matter. Electrons are also fundamental, but protons and neutrons are composite particles made of quarks. Option A incorrectly groups fundamental (electron) with composite (proton) particles, while B is composite.

Criollo is the finest and most prized cacao variety, known for its delicate, complex flavor profile with fruity and nutty notes. It makes up only about 5% of world production due to susceptibility to disease and lower yields. Forastero is the most common (hardy but less flavorful), Trinitario is a hybrid, and Amelonado is a lower-quality Forastero subtype.

John Dalton proposed the first modern atomic theory (1803), establishing the concept that all matter is composed of atoms. J.J. Thomson discovered the electron (1897) and proposed the plum pudding model, while Rutherford discovered the proton and nuclear structure (1911). Dalton's foundational work came first.

J.J. Thomson discovered the electron in 1897 through cathode ray tube experiments, demonstrating the existence of negatively charged subatomic particles. This led to his plum pudding model of the atom. Thomson did not discover the atom (Dalton), proton (Rutherford), or neutron (Chadwick).

South Africa's currency is the Rand (ZAR), introduced in 1961 and named from the Witwatersrand (ridge of white waters) where gold was discovered. The other options are different countries' currencies: Dinar (several Middle Eastern/North African countries), Krona (Sweden), and Somoni (Tajikistan).

Kolleru Lake is one of the largest freshwater lakes in India, located in Andhra Pradesh between Krishna and Godavari deltas. However, 'AP' is ambiguous - it could mean Andhra Pradesh or Arunachal Pradesh. In Andhra Pradesh context, Kolleru Lake (245 sq km) is indeed among the largest lakes, though 'largest' claims can vary by measurement criteria (area, volume, seasonal changes). The ambiguity creates potential confusion.

Ernest Rutherford discovered the proton in 1917-1919 through experiments with nitrogen gas, identifying hydrogen nuclei as a fundamental component of all atomic nuclei. This followed his earlier gold foil experiments that revealed the nucleus. Einstein developed relativity theory, Maxwell formulated electromagnetic theory, and Dalton proposed atomic theory (but didn't discover the proton).

'Ekasila Nagaram' (Single Stone City) is the historical nickname for Warangal, Telangana, referring to the single granite rock formation and the historic Kakatiya dynasty's single-rock fort architecture. Warangal was the Kakatiya capital (12th-14th centuries). The other options are different Andhra/Telangana towns: Annavaram (temple town), Amaravati (new capital), Tirupati (pilgrimage center).
