The figure shows a section of the human ovary. Select the option which gives the correct identification of A and B with function/characteristic:
1. B - Corpus luteum - secretes progesterone
2. A - Tertiary follicle - forms Graafian follicle
3. B - Corpus luteum - secretes LH
4. A - Primary oocyte - it is the prophase - I of the meiotic division
