I had a pretty straight forward line of thinking for this. Cool discolored leg automatically rules out problems elsewhere (all the brain related choices). We know blood has been cut off to the left foot. Specifically, there is an embolus in the arterial blood supply. (Venous would lead to a warm foot)
If you take into account the acute episodes of palpitations, it is plausible to think that she had some sort of A-Fib triggering a blood clot to break off and be sent through the systemic circulation. It then got lodged in the femoral artery cutting off poor g-ma's blood.
Cool, discolored foot with tingling and numbness = blood clot. Cardiac symptoms may indicate that she has some sort of thrombotic disease. The wording of the answer choice isn't great, but none of the other answer choices fit.
