Problem statement: Answer the multiple choice question.
Query: Which drug has a 17.909\% 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) O=C(Cn1ncc2c([nH]c3ccccc32)c1=O)N1CCN(c2ccccn2)CC1
b) Cl.O=C(/C=C/c1cn(-c2ccccc2)nc1-c1cccs1)NCCN1CCOCC1
c) CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)C2CC(=O)N(CCc3ccccc3)C2)cc1
d) O=C1N[C@@H](Cc2ccccc2)C(=O)N2[C@@H]1C[C@@]1(Br)c3ccccc3N(S(=O)(=O)c3ccccc3)[C@@H]21
Answer: a. O=C(Cn1ncc2c([nH]c3ccccc32)c1=O)N1CCN(c2ccccn2)CC1
