In the figure, PQ is the tangent from P to the circle QRS with SR as its diameter. If QRS = \(\theta\)^oand RQP = \(\phi\)^o, which of the following relationships between \(\theta\)^o and \(\phi\)^o is correct

• A.\(\theta\)^o + \(\phi\)^o = 90²
• B.\(\phi\)^o = 90² - 2\(\theta\)^o
• C.\(\theta\)^o = \(\phi\)^o
• D.\(\phi\)^o = 2\(\theta\)^o
• E.\(\theta\)^o + 2\(\phi\)^o
