Task: Answer the multiple-choice question.
Question: Which drug exhibits a 18.171\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CCCNC(=O)C(Cc1ccccc1F)NC(=O)c1ccccn1
[b] CCOc1ccc(/C(O)=C2/C(=O)C(=O)N(CCN(CC)CC)C2c2ccco2)cc1
[c] C=CCn1c(CCNC(=O)c2ccccc2F)nnc1SCC(=O)Nc1ccc(OC)cc1
[d] COc1cccc(C(=O)Nc2cccc(-c3ccc(N4CCOCC4)nn3)c2)c1OC
[e] O=C(CCN1C(=O)c2cccc3cccc(c23)C1=O)NCC1CCCO1
Answer: a. CCCNC(=O)C(Cc1ccccc1F)NC(=O)c1ccccn1
