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.
