I feel B is misleading. Validator should fail with empty input.

I lean towards A. It sets to China but still fails validation.

The default value is China, so it should set to that.

D is the answer. The validator should not be executed if the input is empty, and the creation should be successful.

C seems like the right choice. An empty value should trigger the validator and cause the creation to fail.

I’m a bit confused. If the default is set to China, does that mean it automatically fills in, or does the validator block it?

I practiced a similar question where default values were involved, and I feel like the validator would still run even if the input is empty.

I think if the input is empty, the validator should catch that and fail the creation. So maybe it's option C?

This seems straightforward to me. If the input is empty, the default value of China should be applied. Then the validator would check that and allow it, so option B is the correct answer.

I think the key here is understanding how the default value and validator work together. If the default value sets the country to China, then the validator would likely reject that since it only allows China or American. So I'm leaning towards option C.

I'm a bit confused on this one. The wording about the "picklist" and "validator" is throwing me off. I'll need to re-read the question a few times to make sure I understand all the details.

Okay, let's think this through step-by-step. If the input is empty, does the default value take precedence before the validator runs? Or does the validator check the empty input first?

Hmm, this seems like a tricky one. I'll need to carefully consider the different scenarios and how the validator would interact with the default value.

I believe B makes sense. The default should allow creation if the validator runs fine.
