Task: Answer the multiple-choice question.
Question: Which drug has a 1.875\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) C=CCNC(=O)CCCOc1ccc(C)cc1
b.) CCSC1(SCC)N=C(N)C2(C#N)C(c3ccccc3)NC3=C(CCC3)C12C#N
c.) O=C1c2ccccc2C(Nc2ccc(S(=O)(=O)N3CCCCCC3)cc2)N1c1ccccn1
Answer: a. C=CCNC(=O)CCCOc1ccc(C)cc1
