Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.878% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C1C2CC=C(Cl)CC2C(=O)N1CC1Cc2ccccc2CO1
b COC(=O)C1=C(C(=O)OC)[C@@H]2N(Cc3ccccc3)c3ccccc3[C@@]23C[C@@H](C(=O)OC)N(C(=O)NC2CCCCC2)C3=N1
c CC(=O)c1cc(-c2ccccc2)n(CC(=O)N2CCC(C)CC2)c1C
d CCOc1cc(C(=S)N2CCN(C)CC2)ccc1OCC(=O)N1CCCC1
e CSc1ccccc1NC(=O)c1ccoc1C
Answer: a. O=C1C2CC=C(Cl)CC2C(=O)N1CC1Cc2ccccc2CO1
