Task: Answer the multiple choice question.
Query: Which drug has a 4.173\% 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:

b: O=C1/C(=C\c2ccccc2)SC(=S)N1CCC(=O)N1CCCCC1CCO
c: CCc1c(C)c2ccc(OCC(=O)OC(C)C)c(C)c2oc1=O
d: Cc1nc2c3ccccc3n(CC#N)c(=O)n2n1
Answer: b. O=C1/C(=C\c2ccccc2)SC(=S)N1CCC(=O)N1CCCCC1CCO
