Read the excerpt of a poem below: Daffodils

I wandered lonely as a cloud
That floats on high over the hills,
When all at once I saw a crowd,
A host of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze

Continuous as the stars that shine
And twinkle on the milky way,
They stretched in never-ending line
Along the side of the bay:

Which line is an example of personification?

When all at once I saw a crowd,

Along the side of the bay:

A host of golden daffodils;

Fluttering and dancing in the breeze
