Answer: 1. High concentration of Estrogen

Ovulation is triggered by the LH surge in mid-cycle, and that surge is itself caused by a high level of estrogen from the mature Graafian follicle (positive feedback on the pituitary).

Among the options, only high estrogen is correct as the cause. High progesterone appears after ovulation (luteal phase), and low LH or low FSH would not cause release of the ovum.
