In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding to proteins on its surface.Mice infected with a herpesvirus generally develop keratitis, a degenerative disease affecting part of the eye.Since proteins on the surface of cells in this part of the eye closely resemble those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies to herpesvirus.

Which of the following, if true, gives the greatest additional support to the scientists’ hypothesis?

A.Other types of virus have surface proteins that closely resemble proteins found in various organs of mice.

B.There are mice that are unable to form antibodies in response to herpes infections, and these mice contract herpes at roughly the same rate as other mice.

C.Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis.

D.！There are mice that are unable to form antibodies in response to herpes infections, and these mice survive these infections without ever developing keratitis.

E.Mice that have never been infected with a herpesvirus can sometimes develop keratitis.

D明显是对的啊~

题目是说，老鼠被病毒攻击后会产生一种抗体。
被H病毒攻击的老鼠，眼睛会生病。
而因为H病毒表面的蛋白质和老鼠眼睛的蛋白质很相似，因此有可能是因为老鼠被H病毒攻击后产生的抗体，把眼睛的蛋白质当作H病毒的蛋白质攻击了，所以眼睛会生病。
D选项是说，不会产生抗体的老鼠在被H病毒攻击后，不会眼睛生病，因此加强了原本“眼睛生病是由于抗体”的假设。
