• B. @Value supports relaxed binding of properties, but not property binding through SpEL.
• C. @ConfigurationProperties is preferable over @Value when type-safety during property binding is a concern.
• D. @ConfigurationProperties only bind properties from .properties files, not from .yml files.
• E. @ConfigurationProperties supports relaxed binding of properties, but not property binding through SpEL.

Correct answer: C, E
