The mole (mol) is the SI base unit for amount of substance, used to measure the quantity of chemical entities. Erg measures energy, quintal measures mass (a unit of weight), and light-year measures distance. Only mole is correct for amount of substance.

Power can be measured in both Watts (the SI unit) and Horse Power (a non-SI unit still widely used, especially for engines and vehicles). 1 horsepower ≈ 746 watts. Pascal measures pressure, and Lambert measures luminous intensity or brightness. Both B and D are correct for this MC-2 question.

In extreme desert conditions, a human can typically survive about 72 hours (3 days) without water, though this varies based on temperature, activity level, and individual health. Survival for only 12-24 hours is too pessimistic for most people, while 48 hours is possible but 72 hours represents a more common upper limit before severe dehydration becomes fatal.

Gauss is the unit of magnetic induction (also called magnetic flux density) in the CGS system. It measures the strength of a magnetic field. Electric flux is measured in units like Maxwell or Weber·m², stellar distance in parsecs or light-years, and luminous intensity in candela. Only option A is correct.

Satyajit Ray, the renowned Indian filmmaker, directed a short film titled 'Two' in 1964. The film depicts a conversation between two wealthy men and explores themes of class and privilege. Ray is known for his humanistic cinema, and 'Two' is an example of his short-form work.
