What distinct quality does the speaker attribute to his beloved’s face in this excerpt from william shakespeare’s sonnet 93?

love's face
may still seem love to me, though altered new;
thy looks with me, thy heart in other place:
for there can live no hatred in thine eye,
therefore in that i cannot know thy change.
in many's looks, the false heart's history
is writ in moods, and frowns, and wrinkles strange.
but heaven in thy creation did decree
that in thy face sweet love should ever dwell;

a ) she always looks beautiful.
b) she can express her emotions very well.
c) she can conceal her love very well.
d) she can conceal her moods completely.
