The correct answer is (a) spring tides.
Spring tides are the highest tides that occur when the Moon is closest to the Earth (perigee) and the Sun and Moon are aligned (syzygy). This occurs twice a month, during the new and full moons.
Neap tides are the lowest tides that occur when the Moon is farthest from the Earth (apogee) and the Sun and Moon are at right angles to each other (quadrature). This occurs twice a month, during the first and third quarters of the moon.
Apogean and perigean tides are tides that occur when the Moon is at its closest or farthest point from the Earth, respectively. These tides are not necessarily higher or lower than other tides, but they can be if the Moon is also in a syzygy or quadrature.
Daily and semi-diurnal tides are tides that occur twice a day, once at high tide and once at low tide. These tides are caused by the gravitational pull of the Moon and the Sun.
