Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.005\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CCCS(=O)(=O)N1CCC(C(=O)NCCC(C)C)CC1
(b) O=C(Nc1ccc2oc(-c3ccc4ccccc4c3)nc2c1)c1cccs1
(c) COCc1cc(C)nc(OCC(=O)N/N=C/c2cc(C)n(-c3c(C)cccc3C)c2C)c1C#N
(d) O=C(CN1C(=O)c2ccccc2C1=O)Oc1ccc(F)cc1
(e) O=C(O)c1cccc(-c2ccc(/C=N/n3cnc4sc5c(c4c3=O)CCCC5)o2)c1
Answer: b. O=C(Nc1ccc2oc(-c3ccc4ccccc4c3)nc2c1)c1cccs1
