Answer:
Object 3 has greatest acceleration.
Explanation:
Objects Mass Force
1 10 kg 4 N
2 100 grams 20 N
3 10 grams 4 N
4 1 kg 20 N
Acceleration of object 1,
Acceleration of object 2,
Acceleration of object 3,
Acceleration of object 4,
It is clear that the acceleration of object 3 is and it is greatest of all. So, the correct option is (3).

The term is Social facilitation.
Social facilitation can be defined as an improvement in performance caused by the mere presence of others, it can be further distinguished into two types:
- co-action effects which is a phenomenon where increased task performance is caused by the mere presence of others doing the same task.
- audience effect where performance is increased in the presence of a passive spectator/audience
