Correct option is (C) 3 cm
(A) \(\because\) 4+1 = 5 < 6
\(\therefore\) 4 cm, 1 cm and 6 cm do not form any triangle.
(B) \(\because\) 4+2 = 6 (not strictly greater than 6)
\(\therefore\) 4 cm, 2 cm and 6 cm do not form any triangle.
(C) \(\because\) 4+3 = 7 > 6, 4+6 = 10 > 3 and 3+6 = 9 > 4
\(\therefore\) 3 cm, 4 cm and 6 cm do not form any triangle.
(D) \(\because\) 4+1.5 = 5.5 < 6
\(\therefore\) 4 cm, 1.5 cm and 6 cm do not form any triangle.
