A doubly reinforced rectangular concrete beam has a width of $$300$$ $$mm$$ and an effective depth of $$500$$ $$mm.$$ the beam is reinforced with $$2200\,m{m^2}$$ of steel in tension and $$628\,m{m^2}$$ of steel in compression. The effective cover for compression steel is $$50$$ $$mm$$. Assume that both tension and compression steel yield. The grades of concrete and steel used are $$M20$$ and $$Fe250$$ respectively. The stress lock parameters (rounded off to first two decimal places) for concrete shall be as per IS $$456:200.$$

The depth of neutral axis is

A
$$205.30$$ $$mm$$
B
$$184.56$$ $$mm$$
C
$$160.91$$ $$mm$$
D
$$145.30$$ $$mm$$
