    D)                 10, 20, 40

    Correct Answer: A

    Solution :

               % of s-character in            \[\underset{(s{{p}^{3}})}{\mathop{C{{H}_{4}}}}\,=\frac{100}{4}=25\],  \[\underset{(s{{p}^{2}})}{\mathop{{{C}_{2}}{{H}_{4}}}}\,=\frac{100}{3}=33\],                 \[\underset{(sp)}{\mathop{{{C}_{2}}{{H}_{2}}}}\,=\frac{100}{2}=50\]
