C Correct answer
Explanation

Hundsdiecker reaction and Sandmeyer reaction both proceed via free radical formation as an intermediate. Both Dieckmann condensation reaction and Claisen condensation reaction proceed via the formation of carbanions as an intermediate. Hence, 1 and 2 both the reactions proceed via free radical formation as an intermediate.
