I m getting B

Given answer is D bro

I got \frac{1}{√3}

one doubt bro, why should "P" line on a circle for the angle S1PS2 to be maximum, can you elaborate it, bro can't we take point on the line joining S1 and S2(between them ) for the max angle?

For the max angle the line must be tangent to the circle

Also see yourself by displacing p along the line
