All right, So we're in a nudge for 33 Number 20 and we're looking at severe combined immunodeficiency rice. Let's often abbreviated is s C I. D. This is a very rare genetic disease. About one in AA. Half 1,000,000 people have it. And so it's good that it's rare than what defines this disease in the what well, treats you would need to have tohave It is that both both, uh, t and B cells are either lacking completely. So they're they're missing or nonfunctional rate s 01 way or another, they they're not doing anything for the body on DSO. So you could see immediately in our problem here. That means both b and D are correct. But more than that, it sort of is asking, what do these cells do? Right. So remember the T cells, T cells, prayer role in the in the cell mediated immunity. Also missing those major you're missing that feature. And of course, antibodies. Air produced. Um, right, so So the antibodies are also produced by these cells. And so, by having the missing So having these cells missing also means that there are no antibody production. Eso we're looking at problem 20 here, and And what a child with S c i. D. Would would have it is the answer's gonna be e all of the above. So not only are they missing t and B cells there because they're missing those team B cells that also lacking and antibodies and so mediated immunity.
