a. positive reinforcement
b. negative reinforcement
c. positive punishment
d. negative punishment

The answer is "a. positive reinforcement".

In operant conditioning, positive reinforcement includes the expansion of a reinforcing stimulus following a conduct that makes it more probable that the conduct will happen again later on. At the point when a good result, occasion, or reward happens after an activity, that specific reaction or conduct will be fortified.  

Some of the time positive reinforcement happens normally. For instance, when you hold the entryway open for somebody you may get adulate and a bless your heart. That insistence fills in as encouraging feedback and may make it more probable that you will hold the entryway open for individuals again later on.
