Task: Answer the multiple choice question.
Query: Which drug has a 4.948\% 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: CCn1c(SCC(=O)NC2CC2)nnc1-c1ccccn1
b: O=C(c1c(F)c(F)c(F)c(F)c1F)N1CCN(Cc2ccc3c(c2)OCO3)CC1
c: O=C(NCc1ccc2c(c1)OCO2)C1CCCCC1
d: Cc1ccc(C(=O)CSc2ncn[nH]2)cc1
Answer: c. O=C(NCc1ccc2c(c1)OCO2)C1CCCCC1
