The correct graph representing the variation of total energy $({E_t})$ kinetic energy $({E_k})$ and potential energy $(U)$ of a satellite with its distance from the centre of earth is

$U = \frac{{ - GMm}}{r},K = \frac{{GMm}}{{2r}}$ and $E = \frac{{ - GMm}}{{2r}}$

For a satellite $U,K$ and $E$ varies with $r$ and also $U$ and $E$ remains negative whereas $K$ remain always positive.
