Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 18.376\% 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 other words.
Options:
a O=C1OC(c2ccccc2)c2ccc3ccccc3c21
b CCc1cc(C(=O)NNC(=S)NC2CCCCC2)cs1
c CC(=O)Nc1ccc2sc(NC(=O)CN3CCOCC3)nc2c1
d Cc1ccccc1N(C(=O)c1ccccn1)C(C(=O)NCc1ccccc1)c1cccnc1
Answer: a. O=C1OC(c2ccccc2)c2ccc3ccccc3c21
