Solution

The correct option is A 1 and 2 are correct and 2 is correct explanation of 1
The dimensional analysis does not determine constants and the trigonometrical ratios are also the dimensional constants. hence the dimensional analysis cannot be used for deriving formula that contains trigonometrical ratios.
Hence, option A is correct.
