What will the coalesce function return when provided with multiple arguments?

The coalesce function is designed to evaluate multiple arguments and return the first non-null value it encounters. This makes it particularly useful for handling situations where you may have a series of values, and you want to identify the first valid (non-null) one. For instance, if you were to supply a list of variables to the coalesce function and some of them might be null, the function will skip over these null values and return the first one that contains a valid entry.

This behavior is beneficial in scenarios like setting default values, where you want to ensure that if one value is not available (null), the next available option is utilized. Therefore, in this context, when asking about the return value of the coalesce function in relation to multiple arguments, it is clear that the first non-null argument is the intended return value, making this choice the correct one.
