Explanation:

The High Court of Bombay at Goa said "arguable issues have been raised" in a PIL challenging the "lifetime status of the rank of Cabinet minister". 

• The ministers of the Cabinet head the important ministries of the Union government such as the Defence Ministry, Home Ministry, Finance Ministry, External Affairs Ministers etc. 
• All these ministries play an important role in deciding policies and taking decisions regarding the transaction of the government's business.
• The word Cabinet was inserted in Article 352 of the Constitution by the 44th Constitutional Amendment Act.
• Deputy Ministers are not members of the Cabinet and do not attend cabinet meetings.

Hence only statement 1st is correct.
