Plural or Singular + (s) in title name for dropdown fields

When designing dropdown fields for users that can hold 1 or more values, would you suggest to use the plural form of the title word, or the singular form followed by a (s).

Example 1: Teams

Example 2: Team(s)

In my opinion, the first example implies that the user can select multiple values. On the other hand, the second example shows that a user can also just select 1 value, but it looks not as clean as the first example.

Thanks and kind regards
