Solution

The correct option is D 1
$\sqrt{1 + t a n^{2} θ} \times \sqrt{1 + c o t^{2} θ} \times \sqrt{1 - c o s^{2} θ} \times \sqrt{1 - s i n^{2} θ} = \sqrt{s e c^{2} θ} \times \sqrt{c o s e c^{2} θ} \times \sqrt{s i n^{2} θ} \times \sqrt{c o s^{2} θ} = s e c θ \times c o s e c θ \times s i n θ \times c o s θ = (s e c θ \times c o s θ) \times (c o s e c θ \times s i n θ) = 1 \times 1 = 1$
