Which is the BEST example of an appeal to logos, or reason?

a. A voiceover in a commercial says, "Imagine being in a car that is as silent, swift, and streamlined as a cat—that's a hybrid."

b. An advertisement at the gas station reads, "Hybrids may be more environmentally friendly than electric cars because they rely on kinetic energy, not fossil fuel, to recharge their batteries."

c. Your father always gives good advice. He tells you that it's a good idea to buy a hybrid.

d. A salesperson selling hybrid cars says, "I see hybrids lined up every day in front of luxury restaurants in Beverly Hills. I'm telling you, once you see how the other half lives, you don't go buying a gas guzzler."
