Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.788\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)CN1C(=O)NC(Cc2ccccc2)C1=O
b) C=CCNC(=O)c1cccn1-c1ccsc1C(=O)OC
Answer: b. C=CCNC(=O)c1cccn1-c1ccsc1C(=O)OC
