Final answer:
The phrase likely means that despite the creature's individual features being beautiful, the overall appearance is horrifying, not handsome. The correct answer is option C.
Step-by-step explanation:
From the given text, it is evident that the underlined phrase 'Beautiful!--Great God!' indicates a mixture of shock and horror at the contrast between what was intended and the actual outcome. The phrase is likely to mean C. Handsome! Nothing could be further from the truth! as the creator is horrified at the sight of the creature he has formed—insinuating that though the features were selected for beauty, they became repelling when pieced together. The reference to 'Great God!' suggests a despairing appeal to a higher power, expressing the creator's dismay and regret.
