It is A because it’s the only one that really makes-sense
A subordinate clause, dependent clause or embedded clause is a clause that is embedded within a complex sentence. For instance, in the English sentence "I know that Bette is a dolphin", the clause "that Bette is a dolphin" occurs as the complement of the verb "know" rather than as a freestanding sentence.
Answer:
B). Most of the oil America uses comes from foreign countries.
Explanation:
The statement regarding the <u>'majority of America's demand for oil is catered by oil coming from foreign countries</u>' reflects that the nation is extremely dependent on the oil brought from foreign countries. It <u>signals that the country is unable to fulfill the oil demand of its people itself and forced to import oil from other countries in order to meet the demand</u>. Thus, option B correctly substantiates the claim and hence, <u>option B</u> is the correct answer.
A is not because it displays a full thought. The others could not stand on their own.
