Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.306\% 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(Nc1nc2c(F)cc(F)cc2s1)c1ccccn1
b: Cc1noc(C)c1COC(=O)c1ccc(F)c(S(=O)(=O)N2CCOCC2)c1
c: O=C(NCC(=O)N(c1cccc(F)c1)C(C(=O)NC1CCCC1)c1ccco1)c1ccco1
d: O=C(NNC(=O)c1ccc(NC(=O)c2ccccc2)cc1)Nc1ccccc1
Answer: a. O=C(Nc1nc2c(F)cc(F)cc2s1)c1ccccn1
