In The Tell-Tale Heart, how did the narrator kill the old man?

Read the excerpt below and answer the question. she dwelt among the untrodden ways beside the springs of dove, a maid whom there were none to praise and very few to love: a violet by a mossy stone half hidden from the eye! --fair as a star, when only one is shining in the sky. she lived unknown, and few could know when lucy ceased to be; but she is in her grave, and, oh, the difference to me! (wordsworth, “she dwelt among the untrodden ways”) which option explains a meaning implied by the use of the adjective untrodden in the excerpt? the maid was lost in the woods. the maid lived in a rural setting. the maid was a nature spirit. the maid suffered a life without joy.

Could someone me with this question?
