Determine if each statement is true or false: (b) Substitutional alloys have 'solute' atoms that replace 'solvent' atoms in a lattice, but interstitial alloys have 'solute' atoms that are in between the 'solvent' atoms in a lattice.

Hey everyone where asked which of the following statements is true. Starting out with a, we have solute atoms or sandwich by solvent atoms in the lattice of an interstitial alloy. Now we know that an interstitial alloy is a compound that is formed when an atom with a small enough radius sits in an interstitial hole in a metal lattice. So this statement would be true because that is exactly what A is explaining next. Looking at B, we have solute atoms, substitute solvent atoms in the lattice of a substitution alloy to define a substitution alloy, we know that it is an alloy where in some of the atoms in the metallic crystal of the primary metal are substituted for atoms of other elements. So again, this statement is going to be true since this is exactly what B is describing. So our answer here is going to be answer choice C. Both A and B. Since both statements are true, So I hope that made sense. And let us know if you have any questions.
