Question Analysis
This problem assesses the student's ability to simplify a division of radical expressions with negative radicands.

Key Concept Explanation
When dividing two radicals with the same index, the quotient of the radicands becomes the new radicand. The result can be further simplified if possible. For odd indices, negative radicands are allowed.

Step-by-step Solution
1. Confirm conditions: Index = 3 (odd); radicands ∈ ℝ, -2y ≠ 0; same index.
2. Apply division property:
