Solution
The correct option is D B and D
From the given figures, we find:
The clock shows 6 O'clock. Hence, it is a straight angle.
The pizza with a slice removed shows an angle less than 90°. Hence, it is an acute angle.
The angle between the wings of the fan are greater than 90°. It is not an acute angle.
The mouth of the crocodile makes an angle less than 90 degree. It is an acute angle.
Hence, the angles in the images with the pizza and the crocodile are acute angles.
Hence, the images B and D have acute angles.
