Answer:A. Cannon's central theory
Explanation:
The Cannon-Bard theory of emotion, which is als referred to as Thalamic theory focuses on physiological determination of emotion. This theory state that we feel emotions and then have a physiological reaction to those emotions. According to Cannon's theory emotions can be felt even when the physiological response is absent. Cannon's idea is different from the two factor theory because he suggest that our emotions are not dependent on physiological reactions.
Two factor theory states that physiological arousal brings emotional response whereas cannon's theory state that these two are not dependent on each other.
According to this theory grandma is indeed likely to experience emotions without physiological response.

Marcella's study must meet different requirements EXCEPT convergent validity to establish causality.
<h3>What is causality?</h3>
Causality is an association between a process and an outcome that can be predicted by fulfilling certain requirements.
In this case, Marcella's study must meet variation between cause and effect, time order and removal of other reasons to establish causality.
Convergent validity can be defined as a measure of a scale that is connected with other variables observed in a given construct.
In conclusion, Marcella's study must meet different requirements EXCEPT convergent validity to establish causality.
