In what units is energy density measured?

1. Watts

2. Watts per cubic meter

3. Newtons per meter

4. Joules per cubic meter

2. Relevant equations

E = cB (as derived by Maxwell)

3. The attempt at a solution

This question is so basic yet I'm confused. I thought "B" (magnetic field) had units of Tesla. I thought "c" (speed of light) had units of m/s. I was thinking the answer was Tm / s. I'm particularly confused as to where "per cubic meter" comes into play.
