Solution

The correct option is C Assertion is correct but Reason is incorrect
In $M i r a b i l i s$ $j a l a p a$ , red and white-colored flowers are seen. When they are crossed, in the F1 generation, all flowers are pink colored. This is because of the incomplete dominance of red-colored flowers.
So, the assertion is true, but its reason is not true.
So, option C is the correct answer.
