D is the answer to this question...
I think the answer is a spell checker
At the end of lines may repeat letter sounds.
(Assuming that the clause is <em>if the cat eats</em><u><em> its </em></u><em>food </em>and not <em>If the cat eats </em><u><em>it´s</em></u><em> food.)</em>
First of all, an independent clause is that which expresses an idea by itself. A subordinate clause is the one which depends on another, normally coupled to another by a coordinating conjunction: as,for,by, among others. In this case,we have a conjunction: IF, which in general, joins a sentence with another in which one represents a condition to the second, for example, if it does not rain,we should go swimming.
In the case of <em>if the cat eats its food, </em>we have only one subordinate clause. The reason is that it is not possible to make two sentences out of this one, so it isnot possible to say that there are two independent clauses.
There is not an independet clause only, because although there is only one clause,it is subordinate, the point is that we do not have the clause that it depends on. And so,there is only one clause,we could not say that there is a subordinate and an independent clause either, so the answer is: a subordinate clause only.
