Answer:
A. y-axis only
Step-by-step explanation:
We have the graph of [tex]r=1+5\sin(\theta)[/tex] as given below.
It can be seen that [tex]r=1+5\sin(\theta)[/tex] passes through the points (0,0), (4,0) and (6,0).
Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.
Hence, the axis of symmetry of [tex]r=1+5\sin(\theta)[/tex] is the y-axis only.
