Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.391\% 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] O=C(NC1CCCC1)C(c1cccnc1)N(C(=O)c1csnn1)C1CC1
[b] Cn1c(CN2CCN(c3ccccc3NS(C)(=O)=O)CC2)nc2ccccc21
[c] COc1cccc2c3c(c(=O)[nH]c12)CCC(C)(C)O3
[d] CCOc1cc(C2c3c(-c4ccccc4)n[nH]c3C(=O)N2c2ccc(C(=O)O)cc2)ccc1O
Answer: c. COc1cccc2c3c(c(=O)[nH]c12)CCC(C)(C)O3
