Answer:
B. line 4 <em>That busy archer his sharp arrows tries?</em>
Explanation:
In Sonnet XXX or Sonnet 31, Philip Sydney (1554 – 1586) comments on the pale and sad appearance of moon, and he wonders why it is so. He asks the sun in line 4 whether there is also love which makes him pale and sad. He asks this by alluding to Cupid (the Roman god of love). Cupid is often portrayed with a bow and an arrow, and whoever is shot by that arrow falls in love. So, whoever falls in love is figuratively said to have been shot by Cupid's arrow.
The line 4 alludes to Cupid by calling him "that busy archer". Apart from this mythical allusion there is no allusion in this sonnet.
