    Solution:

    We have to prove that 1+ta n 2 A 1+co t 2 A = tan 2 A  .
    We know the trigonometric identities are
      1+ tan 2 A= sec 2 θ 1+ cot 2 A= cosec 2 θ   Trigonometric ratios are
    secθ= 1 cosθ cosecθ= 1 sinθ sinθ cosθ =tanθ  
    Now, solve the left side of the equation 1+ tan 2 A 1+ cot 2 A = tan 2 A   by using trigonometric identities and trigonometric ratios.
    Hence proved, 1+ tan 2 A 1+ cot 2 A = tan 2 A    .
    Therefore given statement is true.
    Therefore option 1 is true.
