The correct answer is variable interval.
Variable interval means that a particular reinforcement is given after some time has passed. In the case above, grandpa Joe wants to catch a fish, which is his reinforcement. However, he cannot catch it immediately - he has to put his line in the water first, and then wait for some time to feel the line tug. Only then can he get his reinforcement due to variable interval schedule.

Explanation:
Kailash Satyarthi is a renowned campaigner against child labor in India and on the global scene. He was the co-recipient of the Nobel Peace Prize in 2014 along with Malala Yousafzai. Satyarthi began his reform work early in life with his quest for children from less privileged homes to access formal education. His desire to end child labor made him establish a non-profit organization named Bachpan Bachao Andolan also known as Save The Childhood movement in 1980 which ensured that children recruited into child labor by carpet and brick industries were brought back and given a proper education.
On the international scene, Satyarthi pushed for the establishment of the South Asian Coalition of Child Servitude in 1989 and was at the forefront of the Global March Against Child Labor in 1998. The International Labor Organization recognized his efforts and pushed for the convention for the prohibition of child labor in 1999. That same year, he and some others established the Global Campaign for Education. All of these prove that Kailash Satyarthi's contribution also affected the whole world.
