PLS HELP
Which of the following lines from Alfred Lord Tennyson's "The Brook" demonstrates alliteration?

And out again I curve and flow/To join the brimming river
And many a fairy foreland set /With willow-weed and mallow.
And here and there a lusty trout/And here and there a grayling.
And sparkle out among the fern/To bicker down a valley.

I think its B, because "fairy foreland" and "willow-weed". Is that right?
