    Let H be a set of hyperbolas. If a relation R on H is defined by \[R=\{({{h}_{1}},\,{{h}_{2}}):{{h}_{1}},{{h}_{2}}\]have same pair of asymptotes, \[{{h}_{1}},{{h}_{2}}\in H\},\] then the relation R is

    A) Reflexive and symmetric but not transitive             

    B) Symmetric and transitive but not reflexive

    C) Reflexive and transitive but not symmetric            

    D) Equivalence relation

    Correct Answer: D

    Solution :

    [d] R is reflexive as \[{{h}_{1}}R{{h}_{1}}\] (\[{{h}_{1}},{{h}_{1}}\] have same pair of asymptotes) R is symmetric as \[{{h}_{1}}R{{h}_{2}}\Rightarrow {{h}_{2}}R{{h}_{1}}\] R is transitive as \[{{h}_{1}}R{{h}_{2}}\] and \[{{h}_{2}}R{{h}_{3}}\] \[\Rightarrow \,\,\,{{h}_{1}},{{h}_{2}}\]hi, h2 have same pair of asymptotes and \[{{h}_{2}},{{h}_{3}}\]have same pair of asymptotes \[\Rightarrow \,\,\,{{h}_{1}},{{h}_{3}}\] have same pair of asymptotes
