Task: Answer the MCQ question.
Query: Which drug exhibits a 1.242\% 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 CCOC(=O)C1CCCN(C/C(O)=C(\C#N)c2nc(-c3ccc(Cl)cc3)cs2)C1
b O=C(NCc1ccccn1)c1ccc(N2CCCC2)c([N+](=O)[O-])c1
c Cc1c(Cl)cccc1-n1cnc(=O)c2ccccc21
d O=C(Cc1ccc([N+](=O)[O-])cc1)NCc1cccnc1
Answer: c. Cc1c(Cl)cccc1-n1cnc(=O)c2ccccc21
