Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.300\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. Nn1c(SCC(=O)N2CCc3ccccc3C2)nnc1-c1cccs1
b. O=C(O)c1ccc(-n2cccc2)cc1O
c. Cc1oc(-c2cccs2)nc1CS(=O)CC(=O)NCCCOC(C)C
d. O=C(CSc1nnnn1-c1ccc(O)cc1)c1ccc(F)cc1
Answer: d. O=C(CSc1nnnn1-c1ccc(O)cc1)c1ccc(F)cc1
