Yes T increase, k will also increase.
If k increase, then Ea decrease.
If k increase, then Ea decrease.

According to me as T increases, K should increase.

Option A is the right answer because K (rate constant) is directly proportional to the temperature.

k = k0 exp(-E/RT).
ln k =ln k0 + ln (-E/RT).
From the above equation, ln k is inversely prepositional to T.
So increase in T decrease in ln k.
Removing ln will exponentiation decrease in value of k.
ln k =ln k0 + ln (-E/RT).
From the above equation, ln k is inversely prepositional to T.
So increase in T decrease in ln k.
Removing ln will exponentiation decrease in value of k.
