The most accurate answer is WOW , cause for example .. " Wow! That was a good movie! , as you can see .. (Wow) is blocking the rest of the sentence with an expression or known as interjection .. interjections are known to mean , a word that cuts of the sentence for any expression or " feeling " ... it will interject with the sentence with an shouting expression where it cuts off the rest of the sentence to make its totally different one .. here is another example .. " Ouch! That really hurt! " .. Ouch is the interjection in this cause it is showing an expression where it cutted of the other part of this sentence to make another different one ... I hope this helps you and your answer is (A) Wow
