Normal blood pressure is expressed as 120/80 mmHg, where 120 represents systolic pressure (during heart contraction) and 80 represents diastolic pressure (during heart relaxation). This ratio is widely accepted as the healthy baseline for adults. Options A, B, and D don't represent the standard systolic/diastolic relationship correctly.

Most heart attack patients are aged 45 years and above, as cardiovascular risk accumulates over decades due to factors like atherosclerosis, lifestyle choices, and aging. While younger people can have heart attacks, the incidence rises significantly after age 45, especially in men and later in women.

Snowy (also known as Milou in French) is Tintin's faithful white fox terrier companion who appears throughout the comic series. The other options are dogs from different cartoons.

Neon gas emits a characteristic red-orange glow when electrically excited due to its atomic emission lines. The primary wavelength emitted by neon is around 640 nanometers (red), which is why neon signs have their distinctive red appearance. Other colors in 'neon signs' are achieved by using different gases or phosphor coatings.

Helium gas, when electrically excited, emits light in the pinkish-red to yellow-orange range depending on the pressure and conditions. The characteristic helium discharge color is often described as pinkish-red or peach-colored due to the combination of spectral lines including red, yellow, and green wavelengths. This is visible in helium-neon lasers and discharge tubes.

Xenon gas, when electrically excited, emits a characteristic lavender to blue-white light due to its broad emission spectrum across multiple wavelengths. This property makes xenon useful in high-intensity discharge lamps, flash photography, and automotive headlights. The lavender description captures the dominant hue in the visible spectrum of xenon emission.

Krypton gas emits white light when electrically excited because it produces a continuous spectrum with multiple wavelengths across the visible range. This balanced emission creates a nearly pure white light, which is why krypton is used in high-performance flash photography and specialized lighting applications where color accuracy is important. White light appears when all visible wavelengths are present in roughly equal proportions.

JBIMS (Jamnalal Bajaj Institute of Management Studies) is located in Mumbai and is one of India's premier business schools, affiliated with the University of Mumbai. Established in 1965, it has consistently ranked among the top B-schools in India and is known for its strong industry connections and excellent placement record. The institute is named after industrialist Jamnalal Bajaj.

SIP stands for Systematic Investment Plan, a method of investing in mutual funds where you invest a fixed amount regularly (usually monthly) regardless of market conditions. This approach helps in rupee cost averaging - buying more units when prices are low and fewer when prices are high, thereby reducing the average cost per unit over time. It also instills financial discipline and helps build wealth gradually.
