The polar equation is symmetric with respect to the polar axis and has a maximum r-value at θ = π/2. Therefore, the graph must be a circle centered at the origin with a radius of the maximum r-value, which is 11eacce6_2051_8852_9f49_0dff8f860717_TB7896_11. The circle is also symmetric with respect to the polar axis, which confirms choice C as the best option.
