What causes accents and dialects to form? a. language convergence b. regional variations in language development c. the creation of pidgin or creole languages d. increased contact between societies

The way languages work is like evolution. The longer two groups of members of the same species (or that speak the same language) are apart, the more physical (and auditory) differences will arise, because both groups experience different environments, giving them reason to create new words, or they just develop an accent due to isolation since they don't hear their language spoken much in another more "proper" way.

Wow, this site keeps giving me questions asked LAST YEAR. Sorry about the wait, but I'm answering this anyway. Anyway, bye.

B. regional variations in language development

Explanation:

accents and dialects are variations in a language. they usually form due to different ppl use the language in their own way. when enough ppl use that varied way, usually because they are in the same region, it becomes a local accent or dialect.
