Thank you all of you prof.

I have come up with the right answer

Again Thank you for the help , I am grateful to you all

Fruits/flower images is not so clear so correct identity is difficult.

Habit and leaves look like genus Diplotaxis DC., check Diplotaxis acris (Forssk.) Boiss.

Hi,

I second the opinion of Prof. Arvind Singh; It looks like it belongs to Brassicaceae.

Rajeev Kumar Singh prof. Rajeev

I have added new pictures that I hope will be clear

Yes, now it is clear -

Osteospermum vaillantii (Decne.) Norl. (Family - Asteraceae)

Basionym - Tripteris vaillantii Decne.
