Task: Answer the multiple choice question.
Question: Which compound exhibits a -15.534\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(CSc1nnc(-c2cnccn2)n1Cc1ccco1)c1ccccc1
b: CC12CCC(C(=O)N(CSC(=S)N/N=C\c3ccccc3)C1=O)C2(C)C
c: Cn1nnnc1SCSc1nnnn1C
d: COc1ccc2oc(=N)c(C(=O)Nc3ccccc3)cc2c1
Answer: a. O=C(CSc1nnc(-c2cnccn2)n1Cc1ccco1)c1ccccc1
