Answer:
Option C
Extended time
Explanation:
Josepth Walther proposed the social information processing theory, where he said that given sufficient time, Computer-Mediated Communication (CMC) can adapt and still develop interpersonal relationships.
Joseph emphasised the place of extended time as a crucial variable in CMC.
This is because CMC takes at least four times as long to process messages, and it also requires that messages be sent more often. It also needs the use of anticipate future interactions and chronemic cues to establish a good relationship between the two communicators.
Extended time is a key factor needed by online communicators to produce the same amount of impression formation and relationship development as face-to-face communicators
