Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.335\% 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. C=CC(C)N1C(=O)S/C(=C\c2ccc(N3CCOCC3)cc2C)C1=O
b. COc1ccc2c(c1)c1ncn(CCN3CCCC3)c(=O)c1n2C
c. Br.CCCn1c(=N)n(CC(=O)c2ccc([N+](=O)[O-])cc2)c2ccccc21
d. Nc1nnc(SCC(=O)Nc2ccc(N3CCOCC3)cc2)s1
Answer: a. C=CC(C)N1C(=O)S/C(=C\c2ccc(N3CCOCC3)cc2C)C1=O
