Explanation:

TROPICAL EASTERLY JET STREAM.—This jet is closely connected to the Indian and African sum-mer monsoons. The existence of this jet implies that there is a deep layer of warm air to the north of the jet and colder air to the south over the In-dian Ocean. This warm air is of course associ-ated with the maximum heating taking place over India in summer, while the colder air is over the ocean. The difference in heating and cooling and the ensuing pressure gradient is what drives this jet.

So both of the above statements are incorrect.
