Explanation:

2nd statement is correct i.e. La Nina is the cold phase of El Nino, during which the cold pool in the eastern Pacific intensifies and the trade winds strengthen.
La Niña is the positive phase of the El Niño Southern Oscillation and is associated with cooler-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean.

El Niño is a climate cycle in the Pacific Ocean with a global impact on weather patterns. The cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America. Normally, this warm water pools near Indonesia and the Philippines.
