When someone doesn't want you to win

Well the answer really depends on how the host pronounced the word. The word 'read' can be read in two ways either the past tense or the present.

Gotta live the English language

Steed

Answer C but you have to say answer C or it could be wrong if you pronounce it the wrong way

Without hearing the question read out you'd pick 'd' as it contains the word 'read' and can be pronounced either way. ;)

Lead

It's lead say lead both ways and rad both ways

Luckily, the guy says all the words out loud.

Bed

They read out the question and all the answers on that show.

He would get the word read out to him meaning it would rhyme with b,c or d cause if it rhymed with steed it would be to obvious

B or D read pronounced at red or misREAD with Read
