Explanation:

- The general climate of equatorial regions is shaped by their geographical location near the equator.

- Option 1: Hot and humid - Equatorial regions typically experience high temperatures and considerable humidity due to intense sunlight and abundant rainfall.

- Option 2: Warm and humid - While also true, "warm" doesn't fully capture the intense heat experienced in these regions.

- Option 3: Hot and dry - This does not apply to equatorial regions, which usually receive significant rainfall.

- Option 4: Highly seasonal - Equatorial climates experience minor seasonal variations in temperature and have consistent weather patterns.
