Task: Answer the MCQ question.
Query: Which drug exhibits a 4.335\% 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 additional words.
Options:
a: COc1ccc(C(=O)N2CCCCC2C(=O)Nc2ccc(-n3nc(C)cc3C)cc2)o1
b: CCOC(=O)C(C)(C)n1nnc(-c2ccc([N+](=O)[O-])cc2)n1
c: COc1cccc(C(=O)NN/C(C)=C/C(=O)C(F)(F)C(F)(F)C(F)(F)F)c1
d: NC(=S)N/N=C1\CCOc2ccc(F)cc21
Answer: d. NC(=S)N/N=C1\CCOc2ccc(F)cc21
