The answer is A: tightening the string. By doing this, the string will become slightly shorter. A shorter string, when plucked or bowed, will produce a higher pitch. The other answers will have different results. Increasing the thickness, loosening the string, and lengthening the string will all cause the pitch to lower.
A. "tightening the string" is the correct answer.
