Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 9.513\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CCn1nc(C)c(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)c1C
b) Cc1ccc(F)c(CNC(=O)C2CCC(=O)N(CCN3CCOCC3)C2)c1F
c) CCC(=O)N1c2ccccc2C(N(C(=O)CC)c2ccccc2)CC1C
d) O=C(Nc1ccc(Cl)cc1)N(Cc1cccnc1)Cc1ccco1
Answer: a. CCn1nc(C)c(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)c1C
