Correct option is (C) \((\sqrt{3}, \sqrt {27})\)
(A) \((\sqrt{16}, \sqrt 5)\)
\(= \sqrt {16} \times \sqrt 5\)
\(= 4\sqrt 5\)
(B) \((\sqrt{5}, \sqrt 2)\)
\(= \sqrt 5 \times \sqrt 2\)
\(= \sqrt {10}\)
(C) \((\sqrt 3, \sqrt {27})\)
\(=\sqrt 3 \times \sqrt{27}\)
\( =\sqrt{3} \times 3 \sqrt {3}\)
\(= 3\times 3\)
\(= 9\)
(D) \((\sqrt {36}, \sqrt 2)\)
\(= \sqrt{36 } \times\sqrt2\)
\(= 6\sqrt2\)
