HI anksm22,
Based on your answer choice, I think that you probably narrowed this question down to Answers A and B. The missing grammar rule that you needed is based on Parallelism rules. This sentence tells us 2 things about "the restaurant company" - those 2 things have to be written in Parallel "format."
The first thing in both answers is the same:
"the restaurant company HAS recently ADDED many new restaurants...."
The second thing must be parallel to the first. Consider the differences between Answers A and B. Which is parallel?
A: "and its sales HAVE INCREASED dramatically...."
B: "and its sales INCREASED dramatically...."
Answer A properly parallels both verbs, while Answer B does not.
Final Answer: A

According to the sentence, two things have happened to the sales (of the restaurant company):
i) Its sales have increased dramatically
ii) its sales at restaurants open for more than a year have declined
Because have declined is present in the non-underlined portion, we should use have increased in the underlined portion, because both i) and ii) are in the same context.
Understanding this is important, because there is no rule that all part of the sentence should be in the same tense. However, in this case, since the context is the same, the tense used should be the same (in this case, perfect tense).
