Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.021% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] C=CCn1c(N)cc(=O)nc1SCC(=O)Nc1ccc(C(=O)OC)cc1
[b] C=CCn1c(NCc2c[nH]c3ccccc23)nc2ccccc21
[c] COC(=O)[C@@]1(Cc2ccc(F)cc2)[C@H]2c3cc(C(=O)N4CCCC4)n(CCO)c3C[C@H]2CN1C(=O)c1ccccc1
[d] Cc1ccccc1NS(=O)(=O)c1ccc2c(c1)n(C)c(=O)n2C
Answer: a. C=CCn1c(N)cc(=O)nc1SCC(=O)Nc1ccc(C(=O)OC)cc1
