Question

Below are two statements about metals.
1 Metals contain a lattice of negative ions in a sea of electrons
2 The electrical conductivity of metals is related to the mobility of the electrons in the structure. Which is correct?
A Both statements are correct and statement 1 explains statement 2.
B Both statements are correct but statement 1 does not explain statement 2.
с Statement 1 is correct and statement 2 is incorrect.
D Statement 2 is correct and statement 1 is incorrect​
