More simple way of solving this ques
(Sec theta + tan theta)(Sec theta - tan theta )
Since (a+b)(a-b)=a²-b²
Sec²theta- tan² theta
And it is an identity that is equal to 1
Therefore mn =1

Hence option 1 is correct

madam both ko multiple Karo toh sec square -tan square = mn
we know sec square - tan square =1
so mn=1
