A Correct answer
Explanation

In a triple bond, six electrons attract the nuclei with greater force, out of the three types of bond length. This decreases the distance of separation between the two nuclei the most. Hence the bond length is shortest in triple bond.Since, a shorter bond means greater bond strength hence, the energy required to separate the bonded atoms is maximum.
