Licemer1 [7]

A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".

<u>Option: C</u>

<u>Explanation:</u>

Unlike constant reinforcement, partial reinforcement is only strengthened during certain times or time ratios, rather than emphasizing the action every single time. This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time. Thus here a batsman donot plan intentionally to make a century in every cricket match, but it goes random. Although when they need to score high on pressure, they force themselves to stretch as much possible which is not general.
