Multiple Choice

Provide an appropriate response.
-Which of the following pairs of parametric equations will graph a semicircle?

A) $x = \cos \frac { 1 } { 4 } t , y = \sin \frac { 1 } { 4 } t , 0 \leq t \leq 4 \pi$
B) $x = \cos \frac { 1 } { 2 } t , y = \sin \frac { 1 } { 2 } t , 0 \leq t \leq \pi$
C) $x = \cos 2 t , y = \sin 2 t , 0 \leq t \leq \pi$
D) $x = \cos t , y = \sin t , 0 \leq t \leq \frac { \pi } { 2 }$
