d. X
e. S

Answer 1

The letters that have rotational symmetry are O, S, and X.

Step-by-step explanation:

The letters that have rotational symmetry are O, S, and X.

A figure has rotational symmetry if it looks the same after being rotated by a certain angle. In the case of letter O, it has rotational symmetry of order 2, which means it looks the same after rotating it 180 degrees. Letter S has rotational symmetry of order 2 as well. Lastly, letter X has rotational symmetry of order 2 and 4, as it looks the same after rotating it 180 or 90 degrees.
