Task: Answer the multiple-choice question.
Query: Which drug exhibits a 10.320\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CCOC(=O)c1c(C)[nH]c(C(=O)CSc2nnc(CC(C)c3ccccc3)o2)c1C
[b] CCN(CC)c1ccc(/C=C2\C(=O)NC(=S)N(C)C2=O)o1
[c] CCOc1cc(S(=O)(=O)N(CC)CC)ccc1Br
[d] COC(=O)/C=C1\OC(c2ccccc2)=CC1=O
Answer: a. CCOC(=O)c1c(C)[nH]c(C(=O)CSc2nnc(CC(C)c3ccccc3)o2)c1C
