This question is incomplete, here´s the complete question.
"The number and intensity of tropical cyclones in the North Atlantic during a moderate to strong El Nino phase of ENSO is typically"
close to normal.
igher than normal.
lower than normal.
Answer: lower than normal.
Explanation:
A moderate or strong phase of ENSO (El Niño–Southern Oscillation), enhances the inhibition of tropical cyclones (TC) in the North Atlantic due to the increase of vertical wind shear (VWS), subsidence, and decreased relative humidity in the tropical Atlantic.
The warm tropospheric temperatures caused by El Niño in the North Atlantic also creates a disequilibrium with the sea surface temperature (SST), which further inhibits the formation of tropical cyclones (TC).
Answer: (b)
Explanation:
Given
The given equation can be used to determine the length of the line segment AC i.e.
Where, 
Hence, option (b) is correct.
