An x-ray diffraction (xrd) experiment is carried out on a crystalline solid having fcc structure at room temperature. the solid undergoes a phase transformation

An X-ray diffraction (XRD) experiment is carried out on a crystalline solid having FCC structure at room temperature. The solid undergoes a phase transformation on cooling to -20 C and shows orthorhombic structure with small decrease in its unit cell lengths as compared to the FCC unit cell lengths. As a result, the (311) line of the XRD pattern coresponding to the FCC system Q.13 (A) will split into a doublet (B) will split into a triplet (C) will remain unchanged (D)will split into two separate doublets.
