The Table Below Shows the Haplotypes Relative to a Small

The table below shows the haplotypes relative to a small region on chromosome 2 for 10 strains of laboratory mice.All strains are homozygous with respect to the region in question.
$$\begin{array} { | l | l | l | l | l | l | l | } \hline \text { Strain } & \text { SNP1 } & \text { SNP2 } & \text { SNP3 } & \text { SNP4 } & \text { SNP5 } & \text { SNP6 } \\\hline + 1 & \text { A } & \text { G } & \text { G } & \text { T } & \text { A } & \text { C } \\\hline 2 & \text { A } & \text { T } & \text { C } & \text { T } & \text { G } & \text { C } \\\hline 3 & \text { A } & \text { G } & \text { C } & \text { T } & \text { A } & \text { C } \\\hline 4 & \text { A } & \text { G } & \text { C } & \text { T } & \text { A } & \text { C } \\\hline 5 & \text { T } & \text { G } & \text { C } & \text { G } & \text { A } & \text { C } \\\hline \text { 6 } & \text { A } & \text { T } & \text { C } & \text { T } & \text { A } & \text { T } \\\hline 7 & \text { A } & \text { G } & \text { A } & \text { T } & \text { A } & \text { T } \\\hline 8 & \text { T } & \text { G } & \text { C } & \text { G } & \text { G } & \text { C } \\\hline 9 & \text { A } & \text { C } & \text { C } & \text { T } & \text { A } & \text { G } \\\hline 10 & \text { A } & \text { G } & \text { T } & \text { A } & \text { A } & \text { G } \\\hline\end{array}$$
a)Based on the data in the table,what strains are genetically most closely related?
b)How many different haplotypes are represented in the table?
c)What SNP has the highest number of variants/alleles?
