Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 5.895\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(O)C1CC1(c1ccccc1)c1ccccc1
b O=C(O)CCSSCCC(=O)O
c CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccccc3)CC2)=C[C@H](c2ccc(C(F)(F)F)cc2)[C@H]1CCCO
Answer: b. O=C(O)CCSSCCC(=O)O
