Consider 1-D, steady, inviscid, compressible flow through a convergent nozzle. The total temperature and total pressure are $\mathrm{T}_{0}, \mathrm{P}_{0}$ respectively. The flow through the nozzle is choked with
a mass flow rate of $\mathrm{m}_{0} .$ If the total temperature is increased to $4 \mathrm{~T}_{0}$, with total pressure remaining unchanged, then the mass flow rate through the nozzle
(A) remains unchanged.
(B) becomes half of $\mathrm{m}_{0}$.
(C) becomes twice of $\mathrm{m}_{0}$
(D) becomes four times of $\mathrm{m}_{0}$
