The theory of planned behaviour is unique for including the idea that an attitude can be linked more reliably to behaviour if the attitude measure includes the element of perceived behavioural control. Perceived behavioural control is based on:

A) beliefs about resources and opportunities.
B) beliefs about cognition and intentions.
C) beliefs about perspectives and norms.
D) beliefs about attitudes and actions.

Perceived behavioral control in the theory of planned behavior refers to an individual's perception of the ease or difficulty of performing the behavior of interest, which is influenced by beliefs about the presence of factors that may facilitate or impede the performance of the behavior. This includes beliefs about resources and opportunities available to an individual that can help or hinder the execution of the behavior.
