We know that if a standard parabola is shifted by k units along positive y-axis then the equation of translated parabola is given by x2=4a(y−k).
So, according to question the equation of translated parabola shifted by 5 units vertically is given by x2=12(y−5).
Also, upon opening the square we get the equation we get,
⇒x2+60=12y
Hence, option C is correct.
