Let a line LL pass through the point of intersection of the lines bx+10y−8=0bx + 10y - 8 = 0 and 2x−3y=02x - 3y = 0, b∈R−{43}b \in R - \left\{\frac{4}{3}\right\}. If the line LL also passes through the point (1,1)(1, 1) and touches the circle 17(x2+y2)=1617(x^2 + y^2) = 16, then the eccentricity of the ellipse x25+y2b2=1\frac{x^2}{5} + \frac{y^2}{b^2} = 1 is : (a) 25\frac{2}{\sqrt{5}} (b) 35\sqrt{\frac{3}{5}} (c) 15\frac{1}{\sqrt{5}} (d) 25\sqrt{\frac{2}{5}}
