Option (A) is correct. According to the textbook context, the easterlies from either side of the equator converge in the Inter Tropical Convergence Zone (ITCZ). The passage clearly states that near the land surface, the air flows towards the equator as the easterlies, and these easterlies converge at the ITCZ. This convergence happens because of convection caused by high insolation which creates a low pressure zone where winds from the tropics meet. The ITCZ is thus positioned near the Equator, not near the Tropic of Cancer, Tropic of Capricorn, or the Arctic Circle.
