Answer:
A. Fear is an emotional reaction to immediate danger, while anxiety is a longer-lasting state of distress
over anticipated threats.
Explanation:
The article "The Complexity of Fear" tries to give a more specific insight on difference between fear and anxiety, as well as their connections to phobias.
It has been long suggested that fear is a response to a real threat, while anxiety is a fearful response to a situation that doesn't pose a real threat, but is perceived as such.
This article gives a bit different view.
In paragraph 2, the fear is defined as ”...a reaction to something immediate that threatens your security or safety", while paragraph 3 defines anxiety as "...a general state of distress that is longer lasting than fear and usually is
triggered by something that is not specific..."
These definitions seem to go a bit deeper into exploring these emotions and suggest a bit detailed explanation of their origin.
