Which line in the poem london, 1802 by william wordsworth uses metonymy to refer to art and literature?

I believe the correct answer is: "Of stagnant waters: altar, sword, and pen, "

Metonymy is the type of metaphor, figure of speech, which is uses the substitution of the name of an attribute or adjunct for that of the thing meant. In the poem “London” written by William Wordsworth in 1802, the line which uses metonymy to refer to art and literature is the third line: “Of stagnant waters: altar, sword, and pen,” as the pen represents the whole literature in England after Milton’s death.

the answer would either be a or d

i hope this

(i'm bad at sudden poems so don't yell at me i'm trying to represent sadness or something like that but its real hard)

at the age of 4, she thought everything was better.

she was innocent, she was joyful, despite the predictions about the bad weather.

at the age of 10, she started to figure things out.

in life, in its meaning, she started to doubt.

at the age of 14, she was filled with depression, anxiety and fear,

that nobody cared about her, and death was drawing near.

at the age of 17, her sleeves got longer, her will got shorter, until she couldn't take it anymore.

she left this earth with a rope, chair and to the heavens she would soar.
