Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -6.891\% 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=C(O)CSc1ncccc1C(=O)O
b) O=S(=O)(Cc1ccc(Cl)cc1)c1ncc(CO)n1Cc1ccccc1
c) O=C(OCC#CCSc1nnc(-c2cccc3ccccc23)o1)c1ccco1
d) Cc1cc([N+](=O)[O-])ccc1NCc1cccc2ccccc12
Answer: c. O=C(OCC#CCSc1nnc(-c2cccc3ccccc23)o1)c1ccco1
