Explanation:

The Competition Commission of India (CCI) is a statutory body responsible for enforcing the objectives of the Competition Act, 2002.

• The CCI was established under the provisions of the Competition act 2002 (and not under Companies Act, 2013). 
• CCI was established by the Central Government with effect from 14th October 2003, but it became fully functional on 20th May, 2009.
• CCI consists of a Chairperson and 6 other Members appointed by the Central Government.
• The Competition Act, 2007, was enacted after amending Competition Act, 2002, that led to the establishment of the CCI and the Competition Appellate Tribunal.
• The government replaced the Competition Appellate Tribunal (COMPAT) with the National Company Law Appellate Tribunal (NCLAT) in 2017.
• NCLAT is constituted under Section 410 of the Companies Act, 2013.

Hence only statement 2nd is correct.
