The most popular argument regarding the origin of the universe is the Big Bang Theory. It is also called expanding universe hypothesis. Edwin Hubble, in 1920, provided evidence that the universe is expanding(red shift). As time passes, galaxies move further and further apart. Similarly, the distance between the galaxies is also found to be increasing and thereby, the universe is considered to be expanding.
Scientists believe that though the space between the galaxies is increasing, observations do not support the expansion of galaxies.

Explanation:
1. Edwin Hubble, in 1920, provided evidence that the universe is expanding:
- Edwin Hubble, an American astronomer, observed that galaxies are moving away from each other and that the farther a galaxy is, the faster it is moving away.
- This observation led to the conclusion that the universe is expanding, which is a key component of the Big Bang Theory.
2. The distance between the galaxies is increasing:
- One of the implications of the universe expanding is that the distance between galaxies is increasing.
- This can be observed through the redshift of light from distant galaxies, indicating that they are moving away from us.
Therefore, both statements 1 and 2 are true about the Big Bang Theory.
3. The size of the galaxies is increasing:
- It is important to note that while the distance between galaxies is increasing, the size of individual galaxies is not necessarily increasing.
- Galaxies themselves are held together by gravity and do not expand in the same way the universe as a whole does.
Therefore, statement 3 is not true about the Big Bang Theory.
In conclusion, the correct answer is option 'A' (1 and 2 only), as Edwin Hubble's evidence for the expanding universe and the increasing distance between galaxies are key components of the Big Bang Theory.
