Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.907\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCC(C)(C)NC(=O)C(c1ccc(OC)cc1)N(Cc1ccccc1)C(=O)CCC(=O)Nc1cc(C)on1
b CCCCNCC(O)(c1ccc(Cl)cc1)c1ccc(Cl)cc1
c COc1ccc(CCNS(=O)(=O)c2c(N)n(C)c(=O)n(C)c2=O)cc1OC
d CCOCCn1c(=NC(=O)/C=C/c2ccccc2Cl)sc2cc(NC(C)=O)ccc21
Answer: d. CCOCCn1c(=NC(=O)/C=C/c2ccccc2Cl)sc2cc(NC(C)=O)ccc21
