(a) Draw two resonance structures of the cation shown below, shifting only one electron pair in each step

(a) Draw two resonance structures of the cation shown below, shifting only one electron pair in each step. Be sure to include the formal charge on structures B and C.

(b) Use curved-arrow notation on the given structure A to show its conversion to structure B, and then on structure B to show its conversion to structure C.
