Task: Answer the multiple choice question.
Question: Which drug has a 14.914\% 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(NCc1cccc2ccsc12)c1cccs1
(b) O=C(N/N=C/c1ccc(OC(=O)c2ccc([N+](=O)[O-])cc2)cc1)c1cccnc1
(c) CC(C)CNS(=O)(=O)c1ccc(CCC(=O)NCCC2=CCCCC2)cc1
(d) CCOC(=O)c1c(C)[nH]c(C(=O)NCCc2ccc(OC)c(OC)c2)c1C
Answer: a. O=C(NCc1cccc2ccsc12)c1cccs1
