Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.986\% 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 CC1=C(C(=O)OCCOC(C)C)C(c2cc3c(cc2Br)OCO3)CC(=O)N1
b CCOC(=O)CCNC(=O)N1CCCC(C(=O)c2ccc3c(c2)OCO3)C1
c O=C(CCCOc1ccccc1)Nc1nncs1
d Cc1ccc(-c2noc(CSc3nnc(-c4cccs4)n3C)n2)cc1
Answer: c. O=C(CCCOc1ccccc1)Nc1nncs1
