Problem statement: Answer the multiple choice question.
Query: Which drug has a 13.806\% 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.) O=C(CSc1ccccn1)Nc1nc2ccc(Br)cc2s1
b.) O=C(CCc1ccccc1)N1N=C(c2ccncc2)CC1(O)C(F)(F)F
c.) Cc1cc(-c2cccs2)c(C#N)c(=S)[nH]1
d.) CCO[C@H]1OC(C(=O)N2CCN(Cc3ccccc3)CC2)=C[C@@H](c2ccc(C(F)(F)F)cc2)[C@@H]1CCCO
Answer: c. Cc1cc(-c2cccs2)c(C#N)c(=S)[nH]1
