Task: Answer the multiple choice question.
Question: Which drug has a 8.780\% 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=c1[nH]c(=S)n(C2CC2)c(O)c1C=NCCc1ccccc1
b.) CC(=O)O.COc1ccc2nccc(/C=C/c3ccnc4ccc(OC)cc34)c2c1
c.) CO/N=C/NC(=O)Cc1cn(-c2ncc(C(F)(F)F)cc2Cl)c2ccccc12
d.) CC(C)OC(=O)CSc1nc2cccnc2n1C1CCCCC1
Answer: a. O=c1[nH]c(=S)n(C2CC2)c(O)c1C=NCCc1ccccc1
