✓ Umm, quite popular for teenagers.
The error is using a singular count noun 'teenager' after 'for' where a plural noun is required to refer to the group in general. This is a quantifier/count noun issue: when speaking about a category or group, use the plural form 'teenagers' or a quantifier phrase such as 'for teenagers' or 'among teenagers.' Suggestion: say 'popular for teenagers' or 'popular among teenagers.'
