$\huge\underline{\underline{\bf { \red A \green N \pink S\blue W \orange E \purple R \green{...}}}}$

$\longrightarrow \sf \cot \theta - \tan\theta \\ \\ \longrightarrow \sf \frac{ \cos\theta}{ \sin\theta} - \frac{ \sin\theta}{ \cos\theta} \\ \\ \longrightarrow \sf \frac{ { \cos}^{2}\theta - { \sin}^{2}\theta }{ \sin \cos} \\ \\ \longrightarrow \sf\frac{ { \cos}^{2}\theta + { \cos}^{2}\theta - 1 }{ \sin \cos} \\ \\ \longrightarrow \sf\frac{2 { \cos}^{2}\theta - 1 }{ \sin \cos}$

Option ( c ) is correct
