Answer:
C) difficult to catch.
Step-by-step explanation:
In the given excerpt from "The Catching of Unshelled Fish", the narrator states how the unshelled fish is "lively and elusive". Now, elusive means something that tends to evade capture or is hard to define or even comprehend. The narrator also states that it is "past the power of words to portray". So, the best meaning of the word "elusive" in the context of the sentence will be it is "difficult to catch".
