You produce a television spot with a young woman getting ready to dive into a pool that cuts to a gulf of mexico dolphin covered with oil and onscreen the words roll by reading, "doesn't he have the right to swim in clean water too? " what kind of spot is this?

A commercial

Explanation:

A television advertisement or commercial refers to a span of television programming that is produced and paid for by an organization.

Commercials want to transmit a message to the audience, promoting and aiming to a product or service.

In this case, we have a television spot with a woman getting ready to dive into a pool and it cuts to a dolphin covered with oil and the words "Doesn't he have the right to swim in clean water too?".

There is a message that is clearly being sent to the audience and it is the importance of keeping the ocean water clean because this will be good for all the animals that live in the sea.

Therefore, since it is a television advertisement with a message that wants to transmit, we can conclude that this is a commercial.
