A rocket nozzle is designed to produce maximum thrust at an altitude, $H=8 \mathrm{~km}$ from the sea level. The nozzle operates in
(A) under-expanded condition for $H>8 \mathrm{~km}$
(B) under-expanded condition for $H<8 \mathrm{~km}$
(C) sonic exit condition for $H>8 \mathrm{~km}$
(D) unchoked condition for $H<8 \mathrm{~km}$
