Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.780\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1c(NC(=O)Nc2ccc(Cl)cc2)c(=O)n(-c2ccccc2)n1C
b: CC(C)[C@H](NC(=O)OCc1ccccc1)C(=O)OCc1ccccc1
c: Cc1ccccc1CNC(=O)/C=C\C(=O)O
d: CCOC(=O)c1cc2c(N)c(C(=O)c3ccc(Br)cc3)sc2[nH]c1=O
Answer: c. Cc1ccccc1CNC(=O)/C=C\C(=O)O
