Answer:
First Image
Explanation:
Amino acid order is NCC (Nitrogen, alpha carbon with R group attached, and carboxy group).
If we start with methionine, then we write its nitrogen, then alpha carbon and then carboxy and then alanine's nitronge, alpha, carboxy, and end with glycine nitrogen, alpha and carboxy.
I have labelled the "R" groups to show amino acids. First is methionine, then alanine and then glycine.
