I eliminated the rest out the only one that would make sense is a. It’s not c or b because it has nothing to do with tying a sound to the character. And it’s not d because motif is theme so the sound would be overall not just one specific character hope this helped :D
i don't recommend peel off face masks ever, but you should use a hydrating cleanser like the hydrating cleanser by cerave to get soft skin. also use a moisterizer like the daily moisterizer by cerave. they're both really god, and can get you soft skin
