જો $A+B+C+D=2 \pi$ હોય,તો $\sin A+\sin B+\sin C+\sin D=$

  • A
    $4 \sin \left(\frac{A+B}{2}\right) \sin \left(\frac{A+C}{2}\right) \sin \left(\frac{A+D}{2}\right)$
  • B
    $-4 \sin \left(\frac{A+B}{2}\right) \sin \left(\frac{A+C}{2}\right) \sin \left(\frac{A+D}{2}\right)$
  • C
    $4 \cos \left(\frac{A+B}{2}\right) \cos \left(\frac{A+C}{2}\right) \cos \left(\frac{A+D}{2}\right)$
  • D
    $-4 \cos \left(\frac{A+B}{2}\right) \cos \left(\frac{A+C}{2}\right) \cos \left(\frac{A+D}{2}\right)$
