Answer:
From my view, the BEST example of indirect denial is E.
Step-by-step explanation:
In the indirect denial method, We first directly agree with the customer's view point and then give a reason why that customer's view is not 100% accurate.
In E, we can clearly see this, you first say Yes by saying "that's true". and then gives a fair reason why your deal is still the best.
In the Option B, which seems an ok answer too, we don't directly agree with the customer's statement first.
Because of this, Option E is the most applicable answer.
