Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.300\% 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: CCOC(=O)C(=O)N/N=C/c1ccc(F)cc1
b: O=C(c1cccc2nc3ccccc3nc12)N1CCOCC1
c: O=C(NN1CCOCC1)c1ccc(Br)s1
d: CCN(C(=O)CN1CC=C(c2ccccc2)CC1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: c. O=C(NN1CCOCC1)c1ccc(Br)s1
