Reciprocal for a number \(x\), denoted by \(\frac{1}{x}\) or \(x^{-1}\), is a number which when multiplied by \(x\) yields \(1\). The reciprocal of a fraction \(\frac{a}{b}\) is \(\frac{b}{a}\). To get the reciprocal of a number, divide 1 by the number. For example reciprocal of \(3\) is \(\frac{1}{3}\), reciprocal of \(\frac{5}{6}\) is \(\frac{6}{5}\).
Reciprocal of 3 is 1/3.
Reciprocal of 1/17 is 17. Discard.
Reciprocal of \(\sqrt{3}\) is \(\frac{1}{\sqrt{3}}=\frac{\sqrt{3}}{3}\).

Solution:
I. The reciprocal of 3 is 1/3. So, I is correct.
II. The reciprocal of 1/17 is 17. So, II is incorrect.
III. The reciprocal of \sqrt{3} = 1/\sqrt{3} = \sqrt{3}/(\sqrt{3} * \sqrt{3} = \sqrt{3}/3. So, III is correct.
Ans is (D).
