For maximum range, the angle of projection should be 45°.

However, since that's not an option, we need to find the angle closest to 45°.
Among the given options:

• - 35° is closer to 45° than 20°.
• - 60° is closer to 45° than 70°.

However, 35° is closer to 45° than 60°.
So, the correct answer is: 35°.
