Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 19.927% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(O)c1ccccc1C(=O)NCCc1ccc(Cl)cc1
b.) COc1cc(C(=O)N2CCSCC2)ccc1OC1CCN(C(C)=O)CC1
c.) CCc1ccccc1NC(=O)CSc1n[nH]c(C)c1[N+](=O)[O-]
Answer: a. O=C(O)c1ccccc1C(=O)NCCc1ccc(Cl)cc1
