Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.433\% 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 O=C(Cc1cc(=O)[nH]c(=O)[nH]1)NCC1CCCO1
b Fc1ccc(SCCc2ccccn2)cc1
c Cc1ccc(CNS(=O)(=O)c2cn(C)c(=O)n(C)c2=O)cc1
d CC(C)[C@H](NC(=O)OCc1ccccc1)C(=O)N[C@@H](Cc1c[nH]c2ccccc12)C(=O)O
Answer: a. O=C(Cc1cc(=O)[nH]c(=O)[nH]1)NCC1CCCO1
