Question

The use of the phrase "wear one's heart upon one's sleeve" can be traced to these lines from Shakespeare:

Answer 1

I believe the answer is C to openly show inner feelings :)

Answer 2

C would be the correct answer, because in the text Shakespeare writes that: "For when my outward action doth demonstrate 
The native act and figure of my heart "

Another way of saying this would be, "I am openly expressing how I feel."
