The elastic limit of brass is \( 379 \mathrm{MPa} \). What should be the minimum diameter of a brass rod if it is to support a \( 400 \mathrm{~N} \) load without exceeding its elastic limit [JEE (Main) 2019]
(a) \( 1.00 \mathrm{~mm} \)
(b) \( 0.90 \mathrm{~mm} \)
(c) \( 1.36 \mathrm{~mm} \)
(d) \( 1.16 \mathrm{~mm} \)
