Two non-mixing liquids of densities \( \rho \) and \( n \rho(n1) \) are put in a container. The height of each liquid is \( h \). A solid cylinder of length \( L \) and density \( d \) is put in this container. The cylinder floats with its axis vertical and length \( p L(p1) \) in the denser liquid. The density \( d \) is equal to

(a) \( \{1+(n+1) p\} \rho \)
(b) \( \{(2+(n+1) p\} \rho \)
(c) \( \{2+(n-1) p\} \rho \)
(d) \( \{1+(n-1) p\} \rho \)
