Multiple Choice

Evaluate the line integral along the curve C.
- $\int _ { C } \frac { x + y + z } { 5 } d s , C$ is the curve $r ( t ) = 4 t i + \left( 6 \cos \frac { 1 } { 2 } t \right) j + \left( 6 \sin \frac { 1 } { 2 } t \right) k , 0 \leq t \leq 2 \pi$

A) $8 \pi ^ { 2 } + 48$
B) $8 \pi$
C) $8 \pi ^ { 2 } + 24$
D) $8 + 24$
