Task: Answer the MCQ question.
Query: Which drug exhibits a 20.099\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(CSc1nnc(CNC(=O)c2ccccc2)o1)NCc1ccccc1
b COc1ccc(NC(=O)NNC(=O)c2cc3sccc3[nH]2)cc1OC
c O=C(O)/C=C/C(=O)NCc1ccccn1
d N/C(Cc1ccc(Cl)cc1)=N\OC(=O)Cc1ccc([N+](=O)[O-])cc1
e Cc1ccc(S(=O)(=O)N2CCOCC2)cc1C(=O)NC1CCCC1
Answer: c. O=C(O)/C=C/C(=O)NCc1ccccn1
