The dip at a place is delta. For measuring it, the axis of the dip needle is perpendicular to the magnetic meridian. If the axis of the dip needle makes angle `theta` with the magnetic meridian, the apparent dip will be given `tan delta_(1)` which is equal to:

A

tan `delta` cosec `theta`

B

tan `delta` sin `theta`

C

tan `delta` cos `theta`

D

tan `delta` sec `theta`
