Aspring tide occurs twice a year at the new or full moon closest to the vernal and autumnal equinox once a month, or 12 times a year about 26 times per year, at every full and new moon once a year at the first full moon after the vernal equinox

Option (1)

Explanation: A spring tide occurs when the sun, earth and the moon are collinear. It is the condition in which the gravitational pull is exerted on earth by both the sun as well as the moon, from opposite sides. Due to this, there occurs a high tide, in comparison to the regular tide, because of the combination of both the gravitational force. It occurs two time a year on each of the lunar month.

Thus, the correct answer is option (1).

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
