Option C

Explanation:

After energy half life, a radioactive substance reduces its weight by half

After first half life, weight of the sample would be $\frac{W}{2}$

After second half life, weight of the sample would be $\frac{W}{4}$

After third half life, weight of the sample would be $\frac{W}{8}$

After fourth half life, weight of the sample would be $\frac{W}{16}$

After fifth half life, weight of the sample would be $\frac{W}{32}$

After sixth half life, weight of the sample would be $\frac{W}{64}$

Hence Option C is correct
