Consider the given two statements:

I: Morphology of chromosomes is best studied at metaphase
II: At this stage, a chromosome is made up of two sister chromatids, held together at the centromere

1. Both I and II are True and II explains I

2. Both I and II are True but II does not explain I

3. I is True but II is False

4. I is False but II is True
