Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.185\% 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 other words.
Options:
a: COC(=O)C(C)Oc1ccc2c(c1)O/C(=C\c1cccc(Br)c1)C2=O
b: CS(=O)(=O)c1ccc(Cl)c(NC(=O)CN2C(=O)C3CCCCC3C2=O)c1
c: O=[N+]([O-])c1ccc(-c2csc3[n+]2CCS3)cc1.[Br-]
d: CCCOC(=O)c1ccc(NC(=O)Cc2cccs2)cc1
Answer: a. COC(=O)C(C)Oc1ccc2c(c1)O/C(=C\c1cccc(Br)c1)C2=O
