for group, can we use relative pronoun 'who'? .i think who and whom are only used for persons. which and that has to be used for group.
please explain
yes you are right. who and whom are only used for persons.
and here the group is noun modifier or Appositive referring to the group of Bio-conservatives.
So group here refers to people.........hence is correct.
Group is a collective noun here just like team.
