Task: Answer the multiple choice question.
Query: Which compound has a 18.918\% 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: Cc1ccc(Oc2ncccc2CO)cc1
b: CC(C)CC(=O)NN1CCCCC1
c: Cc1ccc2nc(/C(C#N)=C\c3cc(O)ccc3[N+](=O)[O-])[nH]c2c1
d: O=C(CSc1n[nH]c(-c2ccccc2Br)n1)NCCN1C(=O)CSC1=O
e: CC1CCN(C(=O)CN2C(=O)COc3ccc(Cl)cc32)CC1
Answer: d. O=C(CSc1n[nH]c(-c2ccccc2Br)n1)NCCN1C(=O)CSC1=O
