Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.997\% 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: Br.CCOC(=O)/C(C)=N/Nc1nc(-c2ccc(NC(C)=O)cc2)cs1
b: CCOCCn1c(-c2ccccc2)nc2ccccc21
c: O=C(NN1C(=O)/C(=C/C=C/c2ccco2)SC1=S)c1ccncc1
d: CN(C(=O)c1ccc(-c2ccccc2)cc1)C1CCCCC1
Answer: a. Br.CCOC(=O)/C(C)=N/Nc1nc(-c2ccc(NC(C)=O)cc2)cs1
