Step 1: Coordination numbers.
BCC → coordination = 8 → (A) correct.
FCC → coordination = 12, not 6 → (B) incorrect.
Diamond → coordination = 4 → (C) correct.
HCP → coordination = 12 → (D) correct.
Step 2: Conclusion.
Correct set is (A), (C), (D).
Match the LIST-I with LIST-II
| LIST-I | LIST-II |
|---|---|
| A. Mobility of electrons (\(\mu\)) | I. \( Ne^2\tau/m \) |
| B. Drift velocity of electrons (\(v_d\)) | II. \( \mu E \) |
| C. Electrical conductivity of conduction electrons (\(\sigma\)) | III. \( \mu m/e \) |
| D. Relaxation time of electrons (\(\tau\)) | IV. \( 1/\rho ne \) |
