Which of the following literary techniques does byron employ in the line "a heart whose love is innocent! " in "she walks in beauty? " alliteration metonymy synecdoche synesthesia

The correct answer should be synecdoche.
Synecdoche is a figure of speech where a part of something is used to represent the whole thing, or vice versa. In the example above, the word heart refers to her entire being, not only to her heart.
