Solution

The correct option is B 1
The given expression is
$t a n 1^{\circ} . t a n 89^{\circ} . t a n 2^{\circ} . t a n 88^{\circ}$
$∵ t a n θ = c o t (90 - θ)$
$\Rightarrow t a n 1^{\circ} . c o t 1^{\circ} . t a n 2^{\circ} . c o t 2^{\circ}$
$∵ t a n θ = \frac{1}{c o t θ}$
$∴ t a n 1^{\circ} . c o t 1^{\circ} . t a n 2^{\circ} . c o t 2^{\circ} = 1$
