Explanation:
I don't know why, but something keeps telling me the answer is <u>a</u><u> </u><u>c</u><u>o</u><u>m</u><u>p</u><u>u</u><u>t</u><u>e</u><u>r</u><u>.</u>
<u>-</u><u> </u><u>c</u><u>o</u><u>m</u><u>p</u><u>u</u><u>t</u><u>e</u><u>r</u><u> </u>doesn't make sense to me
<h2 /><h2>b and c might be correct</h2>
a computer is the most correct answer according to me, because article a is not specific, same as the question
