At 0 K, the atoms in a crystal are in their lowest energy state and are ordered in a perfect lattice. This means that there is only one possible arrangement of atoms, resulting in zero positional disorder and a perfect crystal lattice structure. As entropy is a measure of the degree of disorder or randomness in a system, a perfect crystal at 0 K has zero entropy, which is denoted as S = 0. Therefore, the correct answer is B: (F1F1F1S1F1F1F10 0.)
