Explanation:

1. In June 2016, the LIGO group of scientists announced the detection of a second set of gravitational waves:
- This statement is correct as the LIGO (Laser Interferometer Gravitational-Wave Observatory) group of scientists did indeed announce the detection of a second set of gravitational waves in June 2016.

2. Gravitational waves were generated due to merger of two black holes at about 1.4 billion light-years distant:
- This statement is also correct. The gravitational waves detected by LIGO were generated by the merger of two black holes approximately 1.4 billion light-years away.

3. Gravitational waves were inserted due to collision of two white dwarf stars at about 14 billion light-years distant:
- This statement is incorrect. Gravitational waves are typically generated by violent events like the merger of black holes or neutron stars, rather than the collision of white dwarf stars. Additionally, the distance of 14 billion light-years mentioned in the statement is not accurate in this context.

Therefore, the correct answer is option 'B' (1 and 2 only).
