The value of

\frac{\left(1+\tan 11^{\circ}\right)\left(1+\tan 34^{\circ}\right)}{\left(1+\tan 17^{\circ}\right)\left(1+\tan 28^{\circ}\right)}

is equal to

View answer and explanation

Correct option: A

Option A (1) is correct because the expression simplifies to 1 using the trigonometric identity (1+tanA)(1+tanB)=2 when A+B=45 degrees.
