Assertion: Metal dificiency defect can be seen in FeO.
Reason: Li compound (LiCl) has pink colour due to F-centre

Options

A. If both assertion and reason are correct and reason is correct explanation for assertion
B. If both assertion and reason are correct but reason is not correct explanation for assertion
C. If assertion is correct but reason is incorrect
D. If both assertion and reason are incorrect

Answer

B

Explanation

Correct Explanation In the crystal of FeO some `Fe^(2+)` ions are missing from the lattice and are repalced by required no. of `Fe^(3+)` ions. This leads to metal deficiency defect
