The Correct Option is D
Solution and Explanation
Step 1: Intersection of the line and the hyperbola.
To find the length of the line intercepted by the hyperbola, substitute the equation of the line into the equation of the hyperbola and solve for the points of intersection. The length is then calculated.
Step 2: Conclusion.
Thus, the length of the intercepted line is \( \frac{6}{\sqrt{10}} \). Hence, the correct answer is option (D).
Final Answer: \[ \boxed{\text{(D) } \frac{6}{\sqrt{10}}} \]
