1) To point the lens of a camera up or down is called:
A) Arc
B)Dolly
C)Pan
D)tilt

D)

Explanation:

Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up/down in a vertical plane.[1] Tilting the camera results in a motion similar to someone raising or lowering their head to look up or down. It is distinguished from panning in which the camera is horizontally pivoted left or right. Pan and tilt can be used simultaneously.[2] In some situations the lens itself may be tilted with respect to the fixed camera body in order to generate greater depth of focus. [3][4]

The camera's tilt will change the position of the horizon, changing the amount of sky or ground that is seen.[5] Tilt downward is usually required for a high-angle shot and bird's-eye view while a tilt upward is for a low-angle shot and worm's-eye view. The vertical offset between subjects can reflect differences in power, with superior being above.

that would be my answer.
