Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.967\% 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) NC(=O)CN1C(=O)NC2(CCCc3sccc32)C1=O
(b) O=C(C1=C[C@H](c2ccc(C(F)(F)F)cc2)C[C@H](OCc2ccc(CO)cc2)O1)N1CCCCCCC1
(c) O=C(NC1CC2CCC(C1)N2C(=O)NCc1ccccc1)NC12CC3CC(CC(C3)C1)C2
(d) CCN(CC)CCCNC(=O)CNC(=S)N(CCCN1CCOCC1)Cc1cccs1
Answer: a. NC(=O)CN1C(=O)NC2(CCCc3sccc32)C1=O
