Answer
Correct answer is C ( 43.9 degrees)
Explanation:
In this problem we have given
weight of photo frame=4.16N
Tension=3N
It is clear that the photo frame is stationary, It means the wires will balance the force due to gravity (the weight).
It means the vertical components of the tension in the wires is equal the total weight.
Because the wires are symmetric, therefore weight of photo frame will be shared equally between wires.
It mean weight supported by each wire=4.16/2
=2.08 N
From figure it is clear that
sin(angle) = 2.08 / 3
angle = arcsin(2.08/3)
angle = 43.9 degrees
Hope this answer will help you
