it the certainty exists we have the pattern
if ...do, then ,,,will do

if the condition is nearly impossible to happen we have 2 pattern
if, ...did , then ... would do
or
if,,, had done, then.... would have done

the first pattern is different from the two. because it is likely to happen.
in fact we have the 4th pattern
if ...do, then....do
this is a fact

in this problem. we realize that choice A and C can not be correct because the present tense "are" is in the second clause while in the if clause simple past is used.

Usage of IF..THEN clauses -

Note - It is not mandatory to use "then" in an "IF THEN clause".
It can be - If...., then outcome
- If....., outcome.
- Outcome, If.....

Now coming to the main point-

1. IF CLAUSE --- SIMPLE PRESENT = THEN CLAUSE --- SIMPLE PRESENT OR SIMPLE FUTURE

2. IF CLAUSE --- SIMPLE PAST = THEN CLAUSE --- SIMPLE PAST OR WOULD + VERB

3. IF CLAUSE --- SIMPLE FUTURE = THEN CLAUSE --- WOULD HAVE + VERB

Hope it helps.
