Equatorial low-pressure belts are also known as Doldrums, and sub-tropical high-pressure belts are known as Horse latitudes.

This statement is correct. The region near the equator characterized by low pressure and weak winds is known as the Doldrums. The sub-tropical high-pressure belts are often referred to as the Horse latitudes.

Prevailing westerlies blow between equatorial low-pressure belts and sub-tropical high-pressure belts.

This statement is incorrect. The prevailing westerlies blow between the sub-tropical high-pressure belts and the sub-polar low-pressure belts.

Trade winds blow between sub-tropical high-pressure belts and sub-polar low-pressure belts.

This statement is also incorrect. Trade winds blow from the sub-tropical high-pressure belts towards the equatorial low-pressure belts.

Therefore, the correct option is 1 only.
