Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.503\% 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 additional words.
Options:
[a] CC(C)CN1CCN(Cc2c(F)cccc2Cl)CC1CCO
[b] O=C(CSCc1ccc(Cl)cc1)N/N=C/c1ccc(Cl)cc1Cl
[c] COc1ccc2cc(C(=O)O)n(CC(=O)c3ccccc3)c2c1
[d] CCOC(=O)CN(C(=O)c1snc(C(N)=O)c1N)C(C(=O)NCCC(C)C)c1ccc(F)cc1
[e] C(=N/N1CCN(c2ccccn2)CC1)\c1ccco1
Answer: a. CC(C)CN1CCN(Cc2c(F)cccc2Cl)CC1CCO
