    Option a. is the correct option.

    Step-by-step explanation:

    In the question given graph is y = x² which is transformed into y = - x²-5

    then we can interpret the graph as below

    1). y = - x²-5 is a function of a parabola.

    2). Since the graph is in the form of y = ax²+b

    Now if we reverse/reflect the graph on x axis then a becomes - a.

    Therefore y = - x² - 5 gets reflected over the x-axis.

    3) Since b represents the y-intercept, if it's negative then graph is shifted down and for positive b graph is shifted upwards. Here - 5 shows the shift of 5 downwards.

    Therefore option a is the correct option.
