## Step 1<br />The problem asks us to identify which group of water deities are known for their ability to shape-shift. The options provided are Scylla, Charybdis, and the Harpies; Amphitrite, Galatea, and Iris; Nereus, Proteus, and Thetis; and None of these.<br /><br />## Step 2<br />We need to consider the mythological backgrounds of each group of deities. <br /><br />## Step 3<br />Scylla, Charybdis, and the Harpies are known for their monstrous and violent nature, but there is no evidence in mythology that they are shape-shifters.<br /><br />## Step 4<br />Amphitrite, Galatea, and Iris are known for their beauty and grace, but again, there is no evidence in mythology that they are shape-shifters.<br /><br />## Step 5<br />Nereus, Proteus, and Thetis are known for their ability to change shape. Nereus is known for his ability to change into different sea creatures, Proteus is known for his ability to change his appearance at will, and Thetis is known for her ability to change her appearance.
