Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.482\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(COCC(=O)NCc1ccccc1)NCc1ccccc1
[b] CCCc1cc(=O)n2[nH]c(C)c(-c3ccccc3)c2n1
[c] CC[C@H](C)[C@@H](CN[C@H](CCCCNC)CNC)NCC1CCCC1
[d] COc1cc(NS(=O)(=O)c2ccc(NC(=S)NC(=O)CC(C)C)cc2)nc(OC)n1
[e] O=C(O)CCCN=C1NC2(CCCC2)Cc2ccccc21
Answer: a. O=C(COCC(=O)NCc1ccccc1)NCc1ccccc1
