Answer:
The most closely central themes of Sonnet 18 are <u>love and mortality</u>.
Explanation:
Shakespeare is saying that the love he has for his partner will live on within this poem, so she, in turn, will be immortal.
It is because of love that the author writes this sonnet. These lines will always praise her beauty. Although the passing time will affect others, death is not going to get her. She is immortal in the lines of the sonnet.
