In the South Atlantic and South Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the reason?

The Intertropical Convergence Zone (ITCZ) remains at or near the equator and does not usually shift southward over the South Atlantic or South Pacific regions.

Therefore, the absence of the ITCZ over these regions is a primary reason for the lack of cyclone formation.

Hence, option B is the correct answer.
