Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.571\% 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 O=C(Nc1cccc(F)c1)c1cc(S(=O)(=O)N2CCC3(CC2)OCCO3)ccc1F
b CC(C)n1nc(C(=O)OCC(=O)c2c[nH]c3ccccc23)c2ccccc2c1=O
c COCCCNC(=O)/C(C#N)=C/c1c(N2CCN(c3ccccc3)CC2)nc2c(C)cccn2c1=O
d Cc1nnc(SCCn2c(Br)nc3c2c(=O)[nH]c(=O)n3C)s1
Answer: c. COCCCNC(=O)/C(C#N)=C/c1c(N2CCN(c3ccccc3)CC2)nc2c(C)cccn2c1=O
