Answer 1

Hint: In order to solve such problems, ensure that you are aware of the clauses and its types. Try to figure out that part of the sentence which can’t stand on its own i.e. it doesn’t make any sense when the other part is removed.

Complete answer:
A clause is a part of a larger sentence containing a subject and a predicate of its own.A Principal Clause is an independent clause which can exist even without a subordinate clause. A Subordinate Clause is called a dependent clause because it cannot exist without the help of the principal clause. It begins with a subordinating conjunction.

Option A is incorrect : The option is incorrect because 'No one knows' is the principal clause.
A Principal Clause is an independent clause which can exist even without a subordinate clause.So the option A is incorrect and we do not use it .
Option B is Correct : Option B is correct because 'who he is' is the subordinate clause beginning with the subordinating conjunction 'who'. It depends on the principal clause for its existence. So option B is correct and we use it as the correct option.
Option C is incorrect : Option C is incorrect because it doesn't make complete sense.So the option we are using this is not the proper one and the option is incorrect and we do not use it .
Option D is incorrect : Option D is incorrect because it is a phrase and not a clause.And hence the option does not match with the given question and we do not use it as the correct option and hence it incorrect

Thus the correct answer is option B.

Note: Using subordinate clauses alone will not make any sense without the existence of the main clause or principle clause. Subordinate clause gives additional information about the main clause, which may not be as much necessary as the main clause gives.
