Consider the production function $Q = \left[ c + a L ^ { \frac { \sigma - 1 } { \sigma } } + b K ^ { \frac { \sigma - 1 } { \sigma } } \right] ^ { \frac { \sigma } { \sigma - 1 } }$ where $c$ is some constant different than zero. This production function exhibits:
A)decreasing returns to scale.
B)constant returns to scale.
C)increasing returns to scale.
D)either decreasing or constant returns to scale, but more information is needed to determine which one.
