Well, it kind of depends what you're advertising for. Here are some of the ones that came up to the top of my head when I thought "commercial".
"Buy now!"
"Parts sold separately."
"Vote ______!"
"_______ is not responsible for any tragedies."
"Consult with your doctor before taking ________."
"*name of the product, and then catchy slogan*"
I think the answer is B, because a mild disposition indicates a calm and steady personality.
The answer is B , help this help…
