Q. The one-liner code that concatenates all strings passed into a function is

• (A) function concatenate() { return String.concat.apply('', arguments); }
• (B) function concatenate() { return String.prototype.concat('', arguments); }
• (C) function concatenate() { return String.prototype.concat.apply('', arguments); }
• (D) function concatenate() { return String.prototype.apply('', arguments); }
