Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.972\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC1CCN(c2nc3nonc3nc2Nc2ccc(F)cc2)CC1
b Cc1ccc(NC(=O)Cc2nnc(SCC(=O)Nc3ccc(N4CCOCC4)cc3)n2C)cc1
c O=C(Nc1ncn[nH]1)c1cccc(F)c1
d S=c1[nH]nc(Nc2cccc(Cl)c2)s1
Answer: d. S=c1[nH]nc(Nc2cccc(Cl)c2)s1
