જો $A + B + C = 180^o$ હોય,તો $\cot \frac{A}{2} + \cot \frac{B}{2} + \cot \frac{C}{2}$ નું મૂલ્ય કેટલું થાય?

  • A
    $\cot \frac{A}{2} \cot \frac{B}{2} \cot \frac{C}{2}$
  • B
    $2 \cot \frac{A}{2} \cot \frac{B}{2} \cot \frac{C}{2}$
  • C
    $4 \cot \frac{A}{2} \cot \frac{B}{2} \cot \frac{C}{2}$
  • D
    $8 \cot \frac{A}{2} \cot \frac{B}{2} \cot \frac{C}{2}$
