The right answer here is
A. The key concept being tested here is that of parallelism, with a side of tenses. The two clauses in this sentence are occurring hand in hand with each other, and hence should take on the same tense in both actions.
A - Simple present, simple present. Gets this spot on!
B - Firstly, "demand" is a singular subject, and should take the singular verb "soars". Furthermore, it goes simple present, present perfect.
OUTC - Present perfect, simple past. This makes no sense at all.
OUTD - Simple present, present perfect. Again, no sense at all.
OUTE - This last sentence may appear to have used the same tense, but the part after the comma is not a coherent clause. In fact, the whole thing is just a noun phrase.
OUTHence,
A is correct - Matoo
