Answer: BC

Explanation:

B. Multiple arguments can be injected into a single method using @Autowired.

This is true because the @Autowired annotation can be applied to methods with arbitrary names and multiple arguments, as shown in the example in Using @Autowired.

C. By default, if a dependency cannot be satisfied with @Autowired, Spring throws a RuntimeException.

This is true because the @Autowired annotation has a required attribute that is true by default, meaning that the dependency is mandatory. If Spring cannot find a matching bean to inject, it will throw a BeanCreationException, which is a subclass of RuntimeException. To avoid this exception, we can set the required attribute to false, which will allow Spring to skip the injection if no matching bean is found
