The correct option is B Low pressure region around which the southeast trade winds and the northeast trade winds converge.
ITCZ is Inter Tropical Convergence Zone. The low pressure region around which northeast trade winds and southeast trade winds converge is called the intertropical convergence zone or ITCZ. ITCZ is generally located near the equator, almost parallel to it. But it moves north or south of the equator with the apparent movement of the sun.
