Identify the subordinate clause in the following:
The man who had left behind his spectacles on the park bench was later identified as the same person who had been accused of the robbery in the nearby bank. [Advanced]
Subordinate clauses start with conjunctions or prepositions and cannot exist without the on the main clause. Here “who...behind” and “who...accused” are dependent on “The...identified”. Hence, Option A and C are correct. The rest of the options do not fit this description, hence incorrect.
