Problem statement: Answer the multiple choice question.
Question: Which drug has a 19.187% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CC[C@H](C)NC(=O)CCCCCn1c(=S)[nH]c2c([nH]c3ccc(OC)cc32)c1=O
(b) O=c1[nH]c2ccc(Cl)cc2c(-c2ccccc2)c1N1CCN(CCO)CC1
(c) O=C(c1ccccc1)N1CCCCCC1
(d) COc1ccccc1NC(=O)/C=C\C(=O)O
Answer: d. COc1ccccc1NC(=O)/C=C\C(=O)O
