    B)                         \[9\]                    

    C)                         \[11\]                                                  

    D)                         \[13\]  

    Correct Answer: A

    Solution :

    Let the four consecutive odd numbers be x, \[x+2,\,x+4\]and \[x+6\]. Their sum = 40 \[\Rightarrow \]               \[x+x+2+x+4+x+6=40\] \[\Rightarrow \]               \[x=7\]
