D) Compound-Complex Sentence
There are three parts to this sentence. The first is a dependent clause "When the fashion critics witness the unveiling of the designer's latest shoes". This is a dependent clause because of the word "when". When makes the sentence need more information. After reading this clause, we are left hanging. The second part of the sentence is "they will shower her with much deserved praise". This is an independent clause. The third part of this sentence is also an independent clause attached to the sentence with the use of the semi-colon (;). It is "she will be named the shoe heiress". This independent clause can stand alone, just like the second part of the sentence. In summary, this sentence has a dependent clause and two independent clauses.
Let's look at the choices:
An independent clause is a sentence that has only one subject and verb phrase. As we've already decided, this sentence is much more than just an independent clause.
Compound sentences have at least two independent clauses. Our sentence also has a dependent clause.
Complex sentences have at least one independent clause and one dependent clause. Our sentence has two independent clauses.
Compound-Complex sentences have at least two independent clauses and at least one dependent clause.
