Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.081\% 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, d, or e without using any other words.
Options:
a. C=CCn1c(SCC(=O)NCc2ccc3c(c2)OCO3)nc2scc(-c3ccccc3)c2c1=O
b. Cc1ccc(C2N(c3ccccc3)C(=S)N3CCCN23)cc1
c. O=C(Nc1nccs1)c1ccc(COc2ccccc2Br)o1
d. O=C(CC1OC(=O)c2ccccc21)Nc1ccc(Cl)c(S(=O)(=O)N2CCCCC2)c1
e. O=C(NC(=S)Nc1sc2c(c1C(=O)O)CCCC2)c1ccccc1
Answer: c. O=C(Nc1nccs1)c1ccc(COc2ccccc2Br)o1
