Question

Which combination is correct for the pairing of Column I and II?

	Column-I		Column-II
$(a)$	$α$ -1-antitrypsin	(i)	Pig
$(b)$	Xenograft	(ii)	Emphysema
$(c)$	Rosie milk	(iii)	Human protein enriched
$(d)$	Toxicity testing	(iv)	More sensitive transgenic animals

α - 1 -antitrypsin is a protease inhibitor that helps protecting alveoli surrounding protein elastin from getting damage by elastase released by WBC. Its deficiency causes emphysema. Xenograft is a process where the graft donor and recipient belong to different organism group. Rosie is the first transgenic cow to produce milk that was enriched with human protein (human alpha lactalbumin). Transgenic animals are used for toxicity testing as they can be made more sensitive to obtain results at a quicker rate.
