Here it's not asked about nominal breaking stress, Breaking stress is obviously less than ultimate stress but in case of the nominal case we should consider the net cross-section area at the time of breaking so in the case of nominal breaking, ultimate stress will be less.

This is for nominal or engineering stress-strain. So the answer will be less than.

Breaking, the stress at which breaking occurs is more than the Ultimate stress. Breaking stress is not less than the ultimate stress.

By stress strain curve ultimate stress is greater than breaking stress. So answer is correct.

If we talk about stress-strain curve in this max. Stress occurs after yield point that is ultimate stress point after that stress goes reducing.

Yes, the breaking stress is less than the ultimate stress.

To sum it up, if you consider the actual cross sectional area at the time of breaking, the stress at which breaking occurs is more than the Ultimate stress.

Right answer @Pranay sb.

No, less only @Apcivilian.
After ultimate stress (maximum stress that the specimen can take) also, material takes less stress with an increased deformation which in turn causes the breaking.

Yes, It should be more.
