A) 0.01

B) 0.015

C) 0.008

D) 0.012

### Explanation:

According to **IS 456:2000**, Plain and Reinforced Concrete Code of Practice,** Clause 26.5.1.1**, the minimum area of **longitudinal column reinforcement shall not be less than 0.8 percent of the gross cross-sectional area of the column.**

**Converting 0.8% to a decimal fraction gives 0.008.**

Therefore, **option C is the correct answer,** as the minimum longitudinal reinforcement area should not be less than 0.008 times the gross cross-sectional area of the column as per IS 456:2000.

Option A, B and D show incorrect minimum area fractions that do not comply with the code requirements.
