Task: Answer the multiple choice question.
Question: Which drug has a -1.878\% 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 other words.
Options:
a: Cc1cccc(C)c1NC(=O)CCS(=O)(=O)c1cccc2nsnc12
b: CSc1nnc(CSCc2ccc(Cl)cc2Cl)n1-c1ccccc1
c: O=C(O)/C=C/c1ccc(O)c(O)c1
d: O=S(=O)(NCc1csc(-c2cccnc2)n1)c1ccc(Cl)s1
Answer: a. Cc1cccc(C)c1NC(=O)CCS(=O)(=O)c1cccc2nsnc12
