**The correct option is (c).**

**Explanation:**

Given mass = 80 kg

Weight = 80 g ( Since mass is not a vector, we have to consider a vector) (g is gravitational acceleration)

Let the weight vector be w = 80 g

Gravitational force is pulling it downwards which it is constrained by the equal and opposite force of the resultant tension of the wire acting in upward direction.

W_{B} = 80 g

T_{1} = W_{B} cos 30^{o} = 80 g x √3/2 = 40√3 g

T_{2} = W_{B} cos 60^{o }= 80 g x 1/2 = 40 g

T_{1}/T_{2} = 40√3 g/ 40 g = √3/1 = √3 : 1
