Factors Affecting Monsoon

**Statement 1 is incorrect.** OMT is measured up to the depth of the 26°C isotherm, but the 129-meter depth mentioned in the southwestern Indian Ocean during January-March is incorrect. The depth of the 26°C isotherm can vary depending on the region and season. **Statement 2 is correct.** OMT collected during January-March helps in predicting the amount of rainfall during the monsoon. It is used to assess whether rainfall will be more or less than the long-term average, as variations in OMT influence monsoon behaviour. Hence, option B is the correct answer.
