Task: Answer the MCQ question.
Query: Which drug exhibits a -21.492\% 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 other words.
Options:
a: CCn1c(C(Cc2ccccc2)NS(=O)(=O)c2ccc(F)cc2)n[nH]c1=S
b: C=C(C)Cn1c(CCn2c3ccccc3c3ccccc32)n[nH]c1=S
c: Cn1c(=O)c2c(nc(CN3CCN(C(=O)c4ccco4)CC3)n2Cc2ccc(F)cc2)n(C)c1=O
d: CC(C)Nc1nc(Cl)nc(NCCOc2ccccc2)n1
Answer: c. Cn1c(=O)c2c(nc(CN3CCN(C(=O)c4ccco4)CC3)n2Cc2ccc(F)cc2)n(C)c1=O
