Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.353\% 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 additional words.
Options:
a: COCCCNC(=O)CN1C(=O)COc2ccc(S(=O)(=O)N3CCOCC3)cc21
b: COc1ccccc1COc1ccc2c(C)c(CC(=O)O)c(=O)oc2c1C
c: O=C(Nc1nc(-c2ccc(F)cc2)cs1)C1CCCO1
d: COc1c(O)cc2c(c1O)C1OC(CO)C(O)C(O)C1OC2=O.O
Answer: c. O=C(Nc1nc(-c2ccc(F)cc2)cs1)C1CCCO1
