Task: Answer the multiple choice question.
Question: Which compound has a 18.337\% 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 C=CCOc1c(Br)cc(C2NC(=O)NC(C)=C2C(C)=O)cc1OCC
b CCOc1ccc(S(=O)(=O)N2CCCCC2)cc1NC(=O)CN1CCCC1c1cccs1
c CCSC1=N/C(=C\c2cccnc2)C(=O)N1c1ccccc1
d Cc1ccc(S(=O)(=O)NCCC(=O)NC(C)CCc2ccccc2)cc1
Answer: a. C=CCOc1c(Br)cc(C2NC(=O)NC(C)=C2C(C)=O)cc1OCC
