Step 1: Understanding the Question:
This question tests knowledge of the water requirement of rice.
Step 2: Detailed Explanation:
The water requirement of the rice crop is approximately 120 cm (C).
Rice is a semi-aquatic crop that requires standing water for most of its growth period.
The actual water requirement varies from 100-150 cm depending on the region and variety.
Other options:
- 25 cm (A): Too low for rice.
- 50 cm (B): Too low for rice.
- 200 cm (D): Too high (possible in some regions).
Thus, the average water requirement is 120 cm.
Step 3: Final Answer:
Thus, the water requirement of the rice crop is 120 cm, which corresponds to option (C).
