b) substage 1: simple reflexes
c) substage 3: secondary circular reactions
d) substage 4: coordination of secondary circular reactions

c) Substage 3: Secondary circular reactions

Explanation:

The Secondary circular reactions occur in between 4 to 8 months after birth. In this stage the child is curious about the world and wants to know what reactions does he/she get when they interact with the world.

Here, Jimmy wants to know what will happen if he puts the rattle in the mouth. He wants to know what will happen if he shakes the rattle differently. Hence, Jimmy is in third substage where Secondary circular reactions occur.
