Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.016\% 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] CC(C)c1ccc(-n2ccnc2SCC(=O)O)cc1
[b] CCN(CC)C(=O)COc1coc(CN2CCN(c3ccccc3F)CC2)cc1=O
[c] Cc1ccc(NC(=O)c2ccccc2)s1
[d] O=C(c1noc2c1CCCC2)N1CCOCC1
Answer: d. O=C(c1noc2c1CCCC2)N1CCOCC1
