Problem statement: Answer the multiple choice question.
Question: Which drug has a -14.121\% 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) Cl.N/N=c1\sc2ccccc2n1-c1ccccc1
(b) O=C(CNC(=O)c1ccncc1)N/N=C/c1cc(Br)ccc1O
(c) COc1ccc(NC(=O)C(NC(=O)Cc2cccs2)c2ccccc2)cc1
(d) CC(NC(=O)c1ccc(Br)o1)C1CC2CCC1C2
Answer: b. O=C(CNC(=O)c1ccncc1)N/N=C/c1cc(Br)ccc1O
