Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 2.720\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCOC(=O)c1c(C)n(C)c2ccc(OCC(O)Cn3nc(C)c(Br)c3C)cc12
b Cc1c(C(=O)O)oc2ccc(S(=O)(=O)N3CC(C)CC(C)C3)cc12
c Cn1c(=O)cc(NCc2ccccc2)[nH]c1=O
d CCN1C=C(Cc2ccc(F)cc2)C2=C(C1)C(c1ccc(F)cc1)C(C#N)=C(N)O2
Answer: a. CCOC(=O)c1c(C)n(C)c2ccc(OCC(O)Cn3nc(C)c(Br)c3C)cc12
