getting independence,it was in 1971 Is it correct in complex form?

Yes, the sentence is correct in complex form.

No, the sentence "getting independence, it was in 1971" is not grammatically correct in complex form.

A complex sentence has a main clause (an independent clause) and one or more dependent clauses. A dependent clause cannot stand alone as a sentence and requires the main clause to make sense.

In the given sentence, there are no subjects and verbs to identify the main and dependent clauses, making it unclear what is the main idea and what is the additional information.

To correct the sentence, you would need to add a subject and verb to the main clause and use a subordinating conjunction to connect the dependent clause. For example:

- Bangladesh gained independence in 1971. (Main clause)
- Bangladesh gained independence when it was liberated from Pakistan in 1971. (Complex sentence with a dependent clause)
