Any object if thrown upwards starts to come downward after reaching a particular height. Therefore, there must be some force that is pulling that object towards the Earth's surface. This argument is based on which of the following means of knowledge?

Correct option is A

The argument presented is an example of Postulation (Arthāpatti). Arthāpatti is a means of knowledge used when an observed fact cannot be explained without positing another fact. In this case, the fact that objects thrown upwards return to the ground leads to the postulation of a pulling force (gravity) as the explanation.
