Which of the following statement is true?

The correct option is D Sum of two acute angles will be either acute or obtuse or right angle.
Sum of 2 acute angles can be acute. For example, 30° + 40° = 70°. 70° is less than 90°, hence it is an acute angle.

Suppose if we consider two acute angles to be 60° and 40°, their sum is 100° which is greater than 90°.

Suppose if we consider two acute angles to be 45°,then their sum will be 90°, which is a right angle.

Therefore, sum of two acute angles will be either acute or obtuse or right angle.
