If {{m}_{1}} and {{m}_{2}}are the slopes of the tangents to the hyperbola frac{{{x}^{2}}}{25}-frac{{{y}^{2}}}{16}=1 which pass through the point (6, 2), then a) {{m}_{1}}+{{m}_{2}}=frac{24}{11} b) {{m}_{1}}{{m}_{2}}=frac{40}{11} c) {{m}_{1}}+{{m}_{2}}=frac{48}{11} d) {{m}_{1}}{{m}_{2}}=frac{11}{20}
