Explanation:

Both statements are incorrect.

• El Nino is associated with a warming of the waters of the eastern tropical Pacific Ocean. It causes increased rainfall in South America.

• However, it is the La Nina, which is associated with a cooling of temperatures in the east-central equatorial Pacific. The La Nina events are associated with rainier-than-normal conditions over southeastern Africa. 

• El Nino Modoki is a different type of El Nino event that forms in the Central Pacific and not the Eastern Pacific. It results in a greater number of hurricanes with a greater frequency while a normal El Nino is associated with a diminishing frequency of hurricanes over the Atlantic Ocean. 

Hence option 4th is correct.
