Explanation:

• Statement 1st is correct: Article 85(1) of the Constitution empowers the President to summon each House of Parliament to meet at such time and place as he thinks fit, but six months shall not intervene between its last sitting in one Session and the date appointed for its first sitting in the next Session.
• Statement 2nd is correct: By convention, Parliament meets for three sessions in a year. The longest, the Budget Session, is held towards the beginning of the year, a three-week Monsoon Session follows from July to August, and then there is the Winter Session, also three weeks long, in November-December. Constitution does not provide that. 
• Statement 3rd is correct: There is no minimum number of days that Parliament is required to meet in a year — in fact, the number of days that Parliament meets has reduced over the years.

Hence option 3rd is correct.
