If `y=x/(log|cx|)` (where `c` is an arbitrary constant) is the general solution of the differential equation `(dy)/(dx)=y/x+varphi(x/y),` then the function `varphi(x/y)` is (a) `( b ) (c) (d)(( e ) (f) x^(( g )2( h ))( i ))/( j )(( k ) (l) y^(( m )2( n ))( o ))( p ) (q) (r)` (s) (b) `( t ) (u)-( v )(( w ) (x) x^(( y )2( z ))( a a ))/( b b )(( c c ) (dd) y^(( e e )2( f f ))( g g ))( h h ) (ii) (jj)` (kk) (c) `( d ) (e) (f)(( g ) (h) y^(( i )2( j ))( k ))/( l )(( m ) (n) x^(( o )2( p ))( q ))( r ) (s) (t)` (u) (d) `( v ) (w)-( x )(( y ) (z) y^(( a a )2( b b ))( c c ))/( d d )(( e e ) (ff) x^(( g g )2( h h ))( i i ))( j j ) (kk) (ll)` (mm)
