What will be the effect of wrong vanishing point in perspective?

Correct answer: Space and proportion will look unbelievable

The direct answer is A: space and proportion will look unbelievable. In perspective drawing, parallel lines that move away from the viewer appear to move toward a vanishing point. This point controls the direction in which roads, edges, buildings and other forms seem to recede. Step by step: first choose the horizon or eye-level line; then place the vanishing point; then draw receding lines toward it. If the point is wrongly placed, lines do not meet in a believable way. Objects may look tilted, stretched, too narrow or wrongly sized, so depth and proportion become unrealistic. Option A is correct because it describes this effect. Option B is wrong because a vanishing point does not decide the colour wheel. Option C is wrong because it does not change the physical or drawn texture. Option D is wrong because perspective cannot make paper thicker. Memory cue: wrong vanishing point means wrong depth and proportion.
