The correct answer is: D. No error
The sentence is grammatically correct. It is a complex sentence with two independent clauses joined by the conjunction “and.” The first clause, “To facilitate exports and improve sales in the domestic market,” is a subordinate clause that modifies the main clause, “some of the improvised fabrics and garments fabricated out from them are displayed in the main pavilion.” The subordinate clause is introduced by the subordinating conjunction “to,” which indicates that the action of the clause is intended
to achieve a goal. The main clause is a simple sentence with a subject (“some of the improvised fabrics and garments fabricated out from them”) and a verb (“are displayed”). The sentence is correctly punctuated with a comma after the subordinate clause.Here is a diagram of the sentence’s structure:
[To facilitate exports and improve sales in the domestic market] [some of the improvised fabrics and garments fabricated out from them] [are displayed in the main pavilion].
The sentence is clear and easy to understand. It conveys the intended meaning without any ambiguity.
