Task: Answer the multiple choice question.
Question: Which drug has a -1.655\% 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] N#CC1=C(S)N(c2ccccc2)C2(CCCCC2)NC1=O
[b] COc1ccccc1CN1C(=O)c2ccccc2C1C(=O)NC1CCC(C)CC1
[c] CCn1nnnc1SCC(=O)c1cc(Cl)ccc1OC
[d] N#Cc1c(N)nc2c(c1-c1ccncc1)CCCCCC2
[e] Nc1nc(-c2ccco2)nn1C(=O)c1cccnc1
Answer: d. N#Cc1c(N)nc2c(c1-c1ccncc1)CCCCCC2
