Two data sets involving the same variables X and Y are given below
X4.14.24.34.44.54.6
Y(set A)10.210.610.911.511.812.2
Y (set B)10.210.611.111.311.812.2
If the slopes and intercepts of the regression lines for the two sets are denoted by $\left(\mathrm{m}_{\mathrm{A}}, \mathrm{m}_{\mathrm{B}}\right)$ and $\left(\mathrm{C}_{\mathrm{A}}, \mathrm{C}_{\mathrm{B}}\right)$ respectively are
(a)$\mathrm{m}_{\mathrm{A}}>\mathrm{m}_{\mathrm{B}}, \mathrm{C}_{\mathrm{A}}>\mathrm{C}_{\mathrm{B}}$
(b)$\mathrm{m}_{\mathrm{A}}<\mathrm{m}_{\mathrm{B}}, \mathrm{C}_{\mathrm{A}}>\mathrm{C}_{\mathrm{B}}$
(c)$\mathrm{m}_{\mathrm{A}}>\mathrm{m}_{\mathrm{B}}, \mathrm{C}_{\mathrm{A}}<\mathrm{C}_{\mathrm{B}}$
(d)$\mathrm{m}_{\mathrm{A}}<\mathrm{m}_{\mathrm{B}}, \mathrm{C}_{\mathrm{A}}<\mathrm{C}_{\mathrm{B}}$
