For the first one is the variant D because ' <span> the largest U.S. state ' it's a developed apposition which mostly are isolated through commas.
For the second one the correct answer it's variant C because '</span><span>a pack of baseball cards' it's also a developed apposition and because the sentence ends in that way we use a dot instead of comma.</span>
