Solution

7) the answer is (c) none of these.. Basically these are removed by the monocyte and macrophages but in hypersensitivity -3 these Ag-Ab complex are not removed hence they cause the hypersensitivity in the body..!!

10) the answer is (a) poison ivy/oak because multiple sclerosis is a type of auto-immunity disorder in human which can occur in hypersensitivite humans who are allergic reactions to metals..!! Wheares other one is a type of delayed one which initiate T-cells in them...!!

15) it is type-3 hypersensitivity because It is only Ab IgG which can form the complex with the protein of the mosquito present inside the serum..!!
