**1. The problem statement, all variables and given/known data**

Assume F⃗ is a vector field and ∇× F⃗ = 0 What can one conclude about F?

A. F=0

B. F=∇

C. F=∇*g

D. F=∇×g

E. Something else

**2. Relevant equations**

None

**3. The attempt at a solution**

I havent really made a proper attemt at solving the problem since I’m confused. I though of curl f = 0 then F should be conservative but that doesn’t always have to be the case. I also thought of Green’s theorem but i think i’d be way of. I could really use a hint
