Solution

The correct option is B 12g
Gram molecular mass is the mass in grams of one mole of a molecular substance.

For example, the gram molecular weight of water H2O is [2×1 (atomic mass of hydrogen) +16 (atomic mass of oxygen)] = 18 g

Similarly, the gram molecular mass of carbon is 12g

Hence, the correct option is C
