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

    ক)
    question mark
    খ)
    asterisk
    গ)
    exclamation mark
    ঘ)
    dollar sign

    Explanation

    The **asterisk** (*\text{*}) is the wildcard symbol used to represent zero or more characters in pattern matching and file searches. This is its standard definition in computing contexts, such as SQL or command-line interfaces. The 'question mark' (?\text{?}) usually represents a single character, not one or more. 'Exclamation mark' (!\text{!}) and 'dollar sign' ($\text{\$}) are typically used for punctuation or variable definition, not as general wildcards for multiple characters.
