"In Disneyland, as ice cream sales increase, so do short tempers. Thus, A) ice cream facilitates short tempers, B) there is a third factor, C) may be coincidental, D) heat is the causal factor, E) B & D"

C & D

Explanation: In the context above, there is no scientific correlation or relationship between ice cream and level of temper. The observed association may be either due to mere coincidence, that is, moment whereby reduction in temper of the subject or participant is witnessed aligns with the the time at which ice-cream is consumed. Coincidental relationships have no scientific relationship and are not fixed, as they usually occur rather naturally in varying circumstances.

The observed correlation might also be due to a confounding or third variable which isn't part of our data but impacting our data, hence, resulting in the observed relationship.
