Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 11.956\% 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 other words.
Options:
a. O=C(c1ccc([N+](=O)[O-])cc1)N1CCN=C1SCc1ccccc1
b. Cc1ncc(CO)c(/C=N/NC(=S)Nc2ccc(C(C)C)cc2)c1O
c. O=C(NCCCc1ccccc1)c1ccncc1
d. Cc1ccc(-c2nnc(N3CCCCC3)c3ccccc23)cc1S(=O)(=O)N1CCN(C)CC1
Answer: b. Cc1ncc(CO)c(/C=N/NC(=S)Nc2ccc(C(C)C)cc2)c1O
