3. Which vitamin is produced by the human skin when
exposed to sunlight?
A) Vitamin A
B) Vitamin C
C) Vitamin D
D) Vitamin E
Answer: C. Vitamin D
Explanation: UVB radiation converts 7-dehydrocholesterol in
the skin to vitamin D₃, which is essential for calcium absorption
and bone health.
4. What is the chemical symbol for gold?
A) Go
B) Gd
C) Au
, Page 3 of 36
D) Ag
Answer: C. Au
Explanation: The symbol Au comes from the Latin word aurum,

5. Which part of a plant conducts photosynthesis?
A) Roots
B) Stems
C) Leaves
D) Flowers
Answer: C. Leaves
Explanation: Leaves contain chloroplasts with chlorophyll, the
pigment that captures light energy for photosynthesis. Some
stems also photosynthesize, but leaves are the primary site.
6. The process by which water changes from a liquid to a gas
is called:
A) Condensation
B) Evaporation
C) Sublimation
D) Precipitation
Answer: B. Evaporation
Explanation: Evaporation occurs when liquid water gains
enough energy to become water vapor. Condensation is the
opposite.
7. Which of the following is a renewable energy source?
A) Coal
B) Natural gas
, Page 4 of 36
C) Solar power
D) Uranium
Answer: C. Solar power
Explanation: Solar power is continuously replenished by the

non-renewable.
8. The human heart has how many chambers?
A) 2
B) 3
C) 4
D) 5
Answer: C. 4

oxygenated and deoxygenated blood.
9. Which of the following is a noble gas?
A) Oxygen
B) Nitrogen
C) Helium
D) Chlorine
Answer: C. Helium
Explanation: Noble gases (Group 18) include helium, neon,
