i think the answer is a because if logan is 4 times older than dylan and dylan is less than 12 years old then that means that logan is older than dylan. which means that since logan isn’t older than 12 dylan also can’t be older than 12 which cancels out both c and d. it can’t be b because if logan is 4 times older than dylan that would most likely mean dylan is less than 3 so the correct answer (for me i might be wrong) is a
hope this helped
