Answer 2

Option B.

A valid class name starts with a Letter and period followed by any number of letters, numbers, or underscores.

Following the guideline makes choosing a valid class name or selectors in CSS relatively simple. Any digits, hyphens, underscores, or letters should be followed by an underscore (_), a hyphen (-), or a letter (a-z)/(A-Z) in a valid name.
