Column-I and Column-II contains four entries each. Entries of Column-I are to be matched with some entries of Column-II. One or more than one entries of Column-I may have the matching with the same entries of Column-II.
Column-I
(A) If radius ratio
\[
x=\left(\frac{r_{c}}{r_{a}}\right)0.155
\]
(P) Co-ordination no. is 8
(B) If \( 0.225 \leq x0.414 \)
(Q) Co-ordination no. is 4
(C) If \( 0.414 \leq x0.732 \)
(R) Co-ordination no. is 6
(D) If \( 0.732 \leq x1 \)
(S) Co-ordination no. is 2
