Why might you use @Profile annotations instead of conditional logic inside a bean's code to handle environment differences?

ABecause @Profile automatically changes database URLs without code.

BBecause conditional logic inside beans is not supported by Spring Boot.

CBecause @Profile controls bean creation at startup, avoiding unnecessary beans and improving clarity.

DBecause @Profile allows beans to be created multiple times in different profiles.

Step-by-Step Solution

Solution:

Step 1: Understand benefits of @Profile
@Profile controls which beans are created based on environment, so only relevant beans exist at runtime.
Step 2: Compare with conditional logic inside beans
Conditional logic runs at runtime and can make code complex and less efficient.
Final Answer:
Because @Profile controls bean creation at startup, avoiding unnecessary beans and improving clarity. -> Option C
