Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.900\% 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.) O=C(Nc1cc(Cl)ccc1N1CCOCC1)C1=COCCO1
b.) Cn1c(=NC(=O)C2CC2)sc2cccc(F)c21
c.) CC(=O)N1c2ccc(S(=O)(=O)N(C)CC(=O)NCc3ccc(C)cc3)cc2CC1C
d.) O=C(O)c1cccc(-n2c(O)c(C=C3N=c4ccccc4=N3)sc2=S)c1
Answer: a. O=C(Nc1cc(Cl)ccc1N1CCOCC1)C1=COCCO1
