Task: Answer the multiple-choice question.
Question: Which drug has a -5.511\% 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 additional words.
Options:
(a) C=CCNC(=O)CSc1cc([N+](=O)[O-])cc(S(=O)(=O)Cc2ccccc2)c1
(b) CCOC(=O)C1=C(N)n2c(s/c(=C\c3cccnc3)c2=O)=C(C(=O)OC)C1c1cccnc1
(c) COc1ccc2c(c1)CCc1c(C(=O)Nc3c(C)nn(Cc4ccccc4)c3C)noc1-2
(d) COc1ccc(CN2C(=O)NC(=O)/C(=C/c3ccoc3)C2=O)cc1
Answer: a. C=CCNC(=O)CSc1cc([N+](=O)[O-])cc(S(=O)(=O)Cc2ccccc2)c1
