Solution:
Remember that we have to preserve the original meaning in A, unless either that meaning makes no sense or we are correcting a grammatical error that changes the meaning. So while other verb tenses may make sense, they may also distort the original meaning.
Also, “due to” is a common GMAT idiom that is used incorrectly. We only use “due to” with nouns or noun phrases. For a verb or clause, we use “because”.

ACE - use "because of" instead of "due to" after verbs
BC: Wordy “need for diverting”
B: Redundant "away"
D: Correct
E: Wordy “need for the diversion of”

Right off the bat, two things caught my eye. First, 'have increased' which made sense with the subject 'efforts', and the present perfect tense should be used because the efforts started in the past but are slowly increasing. Second, 'due to', which is an idiomatic error; it should be replaced with 'because of' since it is modifying the action of increasing and not the noun.

Incorrect for the reason stated above.

Even if we ignore the 'are increasing', which we shouldn't, 'the need for diverting away' just seems awkward.

'Due to' = nope. Bye, option C.

Perfect. Just what I had in mind.

Again, 'due to'.

Hence,  option D is the answer.

Efforts to model drift speed  have increased due to the need to divert  icebergs from oil rigs.

Solution:

(A) have increased due to the need to divert:  here we are talking about an action,  the efforts have increased . Thus, due to is wrong and because should be used.

(B) are increasing because of the need for diverting away:  When we are not sure of the time frame, as in if the action was taken today or some time ago or has been going for some time, we can go for present perfect. "Are increasing" means efforts are increasing right at this moment and it doesn't make much sense. Efforts can be undertaken at this moment or are happening at this moment but they can't be increasing at this moment. An Increase takes place over time.

(C) have increased due to the need for diverting:   here we are talking about an action,  the efforts have increased . Thus, due to is wrong and because should be used.

(D) have increased because of the need to divert: Correct
 
(E) are increasing due to the need for the diversion of:  When we are not sure of the time frame, as in if the action was taken today or some time ago or has been going for some time, we can go for present perfect. "Are increasing" means efforts are increasing right at this moment and it doesn't make much sense. Efforts can be undertaken at this moment or are happening at this moment but they can't be increasing at this moment. An increase takes place over time.

Thus, the answer is D.
