<em>Personification has to with giving human attributes to non-human objects.</em> In this case, there is no such thing as a "physical heartbeat of the group." A group cannot have a heartbeat. However, figures of speech (personification is one of them) are helpful in order to effectively convey a message.
Personification helps send the reader a message that the activist group acts as one body. It lets the audience know that the activist group is united, acts as a solid community, and as one united front. Therefore, using personification creates a stronger tone that effectively conveys a message.
The correct answer is A. use a singular verb.
If a noun is singular, but also collective, it means that it has the form of a singular noun, but refers to more than one entity. However, based on the context, it will either take a singular, or a plural verb.
For example: <em>The team is quite good</em> (where the team is a collective noun referring to all members together) VS. <em>The team are not behaving properly</em> (where this refers to all members individually).
