A is out of scope. There's nothing we can infer about old people in general from Rotelle's criticism of Sims.
D, on the other hand, follows logically. If Rotelle thinks Sims is too old to effectively address the country's issues, then clearly someone who can do this would have to be younger than Sims. If they were the same age or older, Rotelle's criticism would apply.
