Word indicates a possible misspelled word with a red wavy line that appears beneath it, so option B) is the correct one.
As regards option D) the bold green line that appears beneath the word is to show an incorrect grammar structure such as no subject- verb agreement.
Options A) and B) do not apply for misspelled words. A beep sound applies after a grammar and spelling check for example. Also, the spelling dictionary does not pop up automatically as it is available when doing the grammar and spelling check.

The definition of the antecedent of a sentence is that if a word refers to a previous noun or pronoun in the sentence, that pronoun or noun is its antecedent. Let's eliminate some options.

Now we find the relevant part, "his shoes". The pronoun is his. Hence, we have that the antecedent is Samuel.
