Correct Answer: 2

Solution : Given: $\frac{\sin 54^{\circ}}{\cos 36^{\circ}}+\frac{\sec 46^{\circ}}{\operatorname{cosec} 44^{\circ}}$
= $\frac{\sin 54^{\circ}}{\cos (90^{\circ}-54^{\circ})}+\frac{\sec 46^{\circ}}{\operatorname{cosec} (90^{\circ}-46^{\circ})}$
= $\frac{\sin 54^{\circ}}{\sin 54^{\circ}}+\frac{\sec 46^{\circ}}{\sec 46^{\circ}}$
= $1 + 1$
= $2$
Hence, the correct answer is 2.
