Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.125% human ether-à-go-go related gene (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. O=C(COc1cccc(-n2cnnn2)c1)N1CCOCC1
b. CCOC(=O)CC(=O)CSc1nc2ccccc2c(=O)n1-c1ccc(C(=O)NCCOC)cc1
c. CC(=O)c1c(C)nn(C(=O)N2CCOCC2)c1C
d. Cc1cc(C)nc(S/C=C/C(=O)c2ccc(F)cc2)n1
Answer: a. O=C(COc1cccc(-n2cnnn2)c1)N1CCOCC1
