Cot is the inverse of tan. Therefore, the ratios are also inverses. The same goes for csc, which is the inverse of sin.
The tan ∠B = so the cot ∠B =
so the first statement is false.
The sin ∠C = so the csc ∠C =
so the second statement is false.
The tan ∠C = so the cot ∠C =
so the third statement is false.
The sin ∠B = so the csc ∠B =
which reduces to
so the last statement is true!
