A person had an infection of his Peyer's patches and developed intestinal cancer. How could these two events be related?

Peyer's patches filter lymph in the intestine and would have removed the cancer cells.
Peyer's patches contain lymphocytes that may have killed the cancer cells.
Peyer's patches remove abnormal red blood cells, including cancer cells.
Peyer's patches secrete hormones that suppresses the reproduction of cancer cells.

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females
