Question Analysis
This question tests the student's ability to apply the domain restrictions for even roots in the real number system.

Key Concept Explanation
Even roots are only defined for nonnegative bases in the real number system. If the base is negative and the root index is even, the expression is undefined.

Step-by-step Solution
1. Identify the base and the root index: Base = -27, Root index = 4 (even)
2. Check if the base is nonnegative: -27 is negative
3....
