Solution

The correct option is C secθ=20202021
Range of sinθ is [1,1].
Hence, sinθ=2020 is not possible.

Range of tanθ is R.
Hence, tanθ=2020 is a possible value.

Range of secθ is (1][1,).
Hence, secθ=20202021<1 is not possible.

Range of cosθ is [1,1].
Hence, cosθ=20202021<1 is a possible value.
