Task: Answer the multiple choice question.
Query: Which drug has a -5.431\% 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) CCN1/C(=c2/s/c(=C3/C(=O)N(c4ccccc4)N=C3C)n(CC)c2=O)C=Cc2ccccc21
(b) Oc1cccc(/C=N/Nc2ccc(Cl)nn2)c1
(c) CN(C(=O)COC(=O)C1CCN(S(=O)(=O)c2c(Cl)cccc2Cl)CC1)c1ccccc1
(d) O=C(NCCCn1ccnc1)c1ccc(S(=O)(=O)Nc2ccccc2)cc1
Answer: a. CCN1/C(=c2/s/c(=C3/C(=O)N(c4ccccc4)N=C3C)n(CC)c2=O)C=Cc2ccccc21
