Task: Answer the multiple choice question.
Query: Which drug exhibits a 19.210\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1ccccc1-c1nnc(N(C)C(=O)C2CCCO2)s1
b. COc1cc(NC(=O)c2ccnc(N)c2)cc(C(=O)Nc2cccc(C(F)(F)F)c2)c1
c. CN1c2ccccc2C(O)=C(C(=S)Nc2ccccc2)S1(=O)=O
d. N#C/C(=C1\CCCN1)c1ccc2ccccc2n1
Answer: c. CN1c2ccccc2C(O)=C(C(=S)Nc2ccccc2)S1(=O)=O
