Personally, I'd pick A but I'm not 100% sure. Read the stuff at the bottom to see if you'll have a better idea on what the answer could be.
Ok, so first we need to know what iambic pentameter is. Which according to google is
"a line of verse with five metrical feet, each consisting of one short (or unstressed) syllable followed by one long (or stressed) syllable"
Now let's look at the examples.
Before we do know that the letter "u" means unstressed syllables and the symble "/" means stressed syllables.
but if you're still confused I'll put the stressed syllables in bold.
u / u / u / u / u /
Shall I com•pare thee to a sum•mer's day?
Now what this sentence means is this
shall I comPARE thee TO a SUMmer's day?
I know that looks really confusing.... but it really is confusing
But the last example that I have is
The blue truck is behind the cow
behind has two syllables a unstressed and a stressed
u /
be•hind
That's all I got I'm so sorry if this did not help you tbh I didn't even know what a iambic pentameter was until I read your question.
