Official Correct Choice:
Option D: The relationship cannot be determined
Concept: Algebraic Inequality Indeterminacy.

Formula: \(E < M\)

Solution: Doubling \(E\) can make \(2E > M\), \(2E = M\), or \(2E < M\) depending on exact numbers (e.g. if \(E=3, M=10\) vs \(E=8, M=10\)). Thus, relationship is indeterminate.

Why other options are incorrect:

• Options A, B, and C: Assume specific numeric values.
