The first stanza contains an epic simile. "As wasps, provoked by children in their play" establishes the comparison to a hive of wasps provoked to attack by thoughtless children playing near (or directly messing with) the hive. Note that this is a simile because it makes a direct comparison (it uses "like" or "as" to directly compare two ideas)
The answer you are looking for is A, member. The other 3 all have to do with being mindful! While a member just refers to a person. Not to mention there is no "or" in member!
Hope this helps!
