The ______ is a wild card that represents one or more characters.

The correct answer is: B. asterisk

An asterisk () is a wildcard character that represents one or more characters. It can be used to match any character or group of characters in a search string. For example, if you search for "foobar", this will match any string that starts with "foo" and ends with "bar", such as "foobar", "foobaz", and "foofoobar".

The other options are incorrect because:

• A question mark (?) is a wildcard character that represents any single character.
• An exclamation mark (!) is a special character that is used to negate a search string.
• A dollar sign ($) is a special character that is used to match the end of a line.
