Select the correct answer using the code given below:
Pick an option to check yourself.
• Correct Answer: B
• OMT during January-March predicts Indian summer monsoon rainfall with ~80% accuracy, outperforming SST.
• Statement 1 is incorrect: 26°C isotherm depth in south-western Indian Ocean is ~50-100m, not 129m.
• OMT measures thermal energy up to 26°C isotherm depth, not surface temperature alone.
