The correct answer is A. Time will change our youthful appearance, but it will not change true love.
Step-by-step explanation:
In Sonnet 116, Shakespeare explains love always prevails and it is not affected by time. To begin the author mentions "Love's not time's fool", which shows love will not be negatively affected by time, this is also supported by the line "Love alters not with his brief hours and weeks." Besides this, the author clarifies, the time might affect physical appearance this is expressed in "though rosy lips and cheeks Within his bending sickle's compass come". According to this, the idea about time in the poem is that it can change appearance but not love or "time will change our youthful appearance, but it will not change true love."
