Answer
Brief Explanations:
A noun clause functions as a noun in a sentence. In the sentence "Gregor watched, assessing how Sasha reacted to his news", the underlined clause "how Sasha reacted to his news" acts as the object of the gerund "assessing", which is a noun - like function. It tells us what Gregor was assessing (observing in a sense of evaluation). An adverbial clause modifies a verb, adjective, or adverb. A relative clause usually starts with a relative pronoun (who, which, that, etc.) and modifies a noun.
Answer:
It is a noun clause indicating what Gregor was observing.
