C Correct answer
Explanation

JAX-WS (Java API for XML Web Services) is the modern standard that uses JAXB for XML data binding. JAX-RPC is the older, deprecated API. Option A is wrong because both are web service APIs. Option B claims both use JAXB, which is false - JAX-RPC does not. Option D incorrectly states JAX-RPC uses JAXB. Only JAX-WS uses JAXB.
