It is given that a bob is hanging over a pulley inside a car through a string the second end of the string is in the hand of a person standing in the car the car is moving with constant acceleration ‘a’ directed horizontally. Other end of the string is pulled with constant acceleration ‘a’ (relative to car) vertically. We need to find the tension in the string if the θ is constant.
The force on the bob will be in the opposite direction of the motion of the car and also a tension in the string is present.
The forces on the bob of mass m is given by,
It can be seen in the figure that in the y’-y’ direction,
The tension in the string is equal to T = m√ a2 + g2 + ma. The correct answer for this problem is option D.

First we see free body diagram as given in answer
now
we know that। hypotenuse =√ perpendicular^2 + base^2
= √(mg)^2 + (ma)^2
= m √g^2 + a^2
this value will be act as downword force due to gravity
now according to Newtons law of string
T - mg = ma
or T - m√g^2 + a^2 = ma
or T = m√g^2 + a^2 + ma
