Answer: Option C

Explanation:

Opposite angles of a parallelogram are equal. So, the angle opposite to 60° is also 60°.

Now, sum of the 4 angles is 360°. So, sum of the other two opposite angles is {360 - (60 + 60)} = 360 - 120 = 240°

So, each of the other angles is = 240/2 = 120°.

So, the other three angles are 60°, 120°, 120°.
