Hi!
Your answer is D.
A is <u>NOT</u> correct because the only other adjective in the sentence is 'lazy' and that is not a synonym for robust.
B is <u>NOT</u> correct because it doesn't even contain another adjective that could be a synonym.
C is <u>NOT</u> correct because the only other adjective is "tasting" and that is not a synonym for robust.
D <u>IS</u> correct because the only other adjective is "energetic" and that makes the most sense to be the definition of "robust".
<em>P.S. Robust means "healthy" or "strong"</em>
A present participle is formed with the stem of the workd and the suffix -ing and it can have many functions, such as adjective, a part of the verb phrase.
Here all the stentences have a present participle! Here they are:
It is exciting to see the raised head of a dolphin in the water!
exciting - it can be seen as a present participle or adjective
When dolphins are above the water, they are breathing air.
breathing - this is definitely a present participle
Having adapted to pressure changes,
dolphins’ lungs enable them to dive below the ocean’s surface.
here "having" is the participle"
Swimming
dolphins need to break the surface for air every two minutes.
here "smimming" is the participle.
So the answer depends on which word was underlined!
Aesop was the writer of ancient greek fables.
