I'm pretty sure it's larva hope this helps
Answer: Option (a) is correct.
Explanation:
Molecules of sugar given = 
According to Avogadro's number it is known that 1 mole contains
.
Therefore, calculate the moles of sugar present in the sample as follows.
Number of moles = 
= 0.25 mol
Thus, the moles of sugar present in the sample is 0.25 mol.
