Which technique is suitable for painting soft flower petals in watercolour?

Correct answer: Apply controlled colour on a damp surface

Soft petals are best created with a controlled wet-on-damp approach. A slightly damp paper surface allows transparent colour to spread gently, producing delicate edges and gradual transitions without losing the petal shape. Option A is correct; the artist can place stronger colour near the centre and lighter colour toward the edge. Thick black paint, dry brush alone, and scratching would create hard, rough, or damaged effects rather than soft petals.
