B Correct answer
Explanation

JavaScript arrays can be created using the Array constructor with comma-separated values in parentheses. Option B demonstrates the correct syntax: new Array("tim","kim","jim") creates a 3-element array. Options A, C, and D all use incorrect syntax - option A incorrectly uses an equals sign, option C uses colons and numbers, and option D tries to use associative array/object key syntax which doesn't work with the Array constructor.
