Answer:
2)B–, 12
Explanation:
Among the four options given in question statement, the correct option is 2
A crystalline solid with ionic bonding would follow a FCC structure with the positive ions in the octahedral void
In such configuration, the first nearest neighbour would be a negative ion B- and they would be 6 in number and then the other neighbours, sitting on the edges would be 12
