    Well I can't see the compelete question but it looks as though you should work out y'' and y' and substitute them into the expressions in the answers selections to which which one is consistent.

    By consistent I mean that the RHS = the LHS.

    For instance for option (a) do you think the y'' you have worked out is equal to the square of the y' you have worked out, divided by y?
