Let's see how many packs of each item we can make and what's left over. That's the remainder.
287 = 6(287/6) = 6(47) + 5
143 = 3(143/3) = 3(47) + 2
341 = 7(341/7) = 7(48) + 5
So on that 48th pack we have 5 people markers so need 1 more and 2 dice, so we need one more. We have enough teleport markers for the 48th pack.
Choice A.
