Answer:
Sentence D is an example of a complex sentence.
Explanation:
A complex sentence contains one independent clause and at least one dependent clause. The difference between an independent clause and a dependent one is that the former can stand alone as a sentence as it represents a complete thought. The ungrammaticality of sentence A proves this point. As you can see, without the independent clause (B), the dependent clause (A) does not represent a complete idea, it depends on the main clause to complete its meaning (C).
A) *Because it is cruel
B) The death penalty should be abolished
C) Because it is cruel, the death penalty should be abolished
When it is a linking verb, it contains a adjective right after the main verb (is/feel/were/was) and must express the person.
Example: I feel sad.
"Feel" is the main verb in this sentence and it is expressing ones emotion. So if that is the verb, then "sad" is the adjective. Because of this example, you can see that
"Were" in the sentence is the main verb and after those are the adjectives ( tired and dirty). Therefore, you just found a linking verb.
Then answer would be (A)
