Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.030\% 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. O=C1c2ccccc2C(=O)N1CC1CCCO1
b. CCCCN1CCNC[C@@H]1Cc1ccccc1
c. COc1ccc(CC(=O)Nc2c3c(nn2C(C)(C)C)CS(=O)(=O)C3)cc1
d. Cc1cccc(NC(=O)C2C3C=CC(O3)C2C(=O)O)c1
Answer: a. O=C1c2ccccc2C(=O)N1CC1CCCO1
