The Correct Option is B
Solution and Explanation
Step 1: Identify network solids.
Network solids are solids in which atoms are connected by strong covalent bonds throughout the crystal.
From the given list, network solids are:
\[ AlN,\; diamond,\; SiO_2 \] So, number of network solids is
\[ 3 \]
Step 2: Identify ionic solids.
Ionic solids are made up of positive and negative ions held together by strong electrostatic forces.
From the given list, ionic solids are:
\[ CaF_2,\; MgO,\; ZnS,\; NaCl \] So, number of ionic solids is
\[ 4 \]
Step 3: Classify the remaining substances.
\[ H_2O(ice) \text{ is a molecular solid} \] \[ Cu \text{ and } Ag \text{ are metallic solids} \] \[ CCl_4 \text{ is a molecular solid} \]
Step 4: Final conclusion.
Hence, the number of network solids and ionic solids respectively is
\[ \boxed{3,\,4} \]
