How is correct proportion maintained when enlarging a leaf for a scientific drawing?

Answer and explanation

Correct answer: By enlarging all parts in the same ratio

Uniform enlargement preserves proportion. If the original length, width, stalk, outline, and vein spacing are all multiplied by the same scale factor, their relationships remain unchanged while the whole leaf becomes larger. Enlarging only the stalk, removing veins, or changing width without length distorts the specimen. Thus option A describes the correct scientific drawing method.
