Explanation:

Only statement 3rd is correct.

• Both the President and the Governor have been vested with sovereign power of pardon by the Constitution. 
• Under Article 72, the President can grant pardons, reprieves, respites or remissions of punishment or suspend, remit or commute the sentence of any person.
• The President can pardon a sentence imposed by a court-martial. However, the Governor cannot pardon a sentence inflicted by a court-martial. 
• The President can also Pardon if the sentence is for an offence under any law relating to the Union government’s executive power, and in all cases of death sentences.
• Under Article 161, a Governor can grant pardons, reprieves, respites or remissions of punishment, or suspend, remit or commute the sentence.
• This can be done for anyone convicted under any law on a matter which comes under the State’s executive power.

Hence option 3rd is correct.
