Explanation:

Goa Revolution Day was celebrated on June 18, 2019.

Although Goa got its freedom on 19 December 1961 from Portuguese, the first blow for Goa’s liberation from the Portuguese in 1961 was struck on 18 June 1946 by Ram Manohar Lohia. In June 1946 he paid a friendly visit to the Goan academician and writer, Dr Juliao Menezes. When the Goans heard of his arrival, they rushed to Menezes’s residence to apprise Lohia of the plight of the Goans.

On June 18, 1946, defying the ban on public meetings, Lohia launched the Civil Disobedience Movement to gain back the lost civil liberties of Goans. Hence 3rd is correct.
