Transfer Major Decision -- How bad is it to major in a class where I got a B?

Hi I’m currently a first-year community college student trying to transfer into USC as a sophomore. My first major choice is Health and Human Sciences at Dornsife but I haven’t completed the “recommended coursework” for admission so I was debating if I should put down Psychology as my major and transfer into H&HS later on since they are both in Dornsife. The only problem is that I got a B in Psych. How bad is it to major in a class where I got a B in?

Also, I was planning to take Sociology next semester so I was debating if I should do that as my major because I am almost certain I can get an A in that class. Would it be suspicious to be a soc. major if all my extracurriculars are med-field oriented (volunteering at the hospital, hospital internship, clubs, etc.)?
