The wording on the first rule is annoyingly opaque :-/
The first rule says: If a purple bead is adjacent (next to) to a yellow bead, any bead that immediately follows and any bead that immediately precedes the pair must be red.
This rule does not mean that any PY pair must be bookended by two red beads. It means that IF a bead precedes the PY pair, then that bead must be read. Similarly, IF a bead follows the PY pair, then that bead must be red.
(C) does not violate that rule, since no bead precedes the PY pair. The bead that follows the pair is, indeed, red.
(A) violates the third rule (R and O are adjacent)
(B) violates the second rule (R and R are adjacent)
(D) violates the first rule (G follows the PY pair)
(E) violates the last rule (there’s no O)
