Question

Which of the following statements about the male okapi's horns is true?

Option 1: They are bare of skin from birth.
Option 2: They are about one foot long.
Option 3: They develop between the second and fourth years.
Option 4: Their tips become polished with time.

Answer 1

The true statement about male okapi's horns is that they develop between the second and fourth years, are covered with skin, shorter than one foot, and the tips may become polished with time. The correct option is 3.

Step-by-step explanation:

Among the statements provided about the male okapi's horns, the true statement is Option 3: They develop between the second and fourth years.

Okapis, which are relatives of the giraffe, have skin-covered horn-like structures called ossicones. Unlike the statement in Option 1, these are indeed covered with skin. Option 2 is incorrect because the horns are much shorter than one foot long.

Lastly, Option 4 has some merit because, as with giraffes, the tips can become more worn or polished with time due to activities such as fighting or rubbing against trees, but this is not the primary identifying feature of their development.
