Based on this cladogram, which pair of organisms are likely to share the most similarities with each other?

The image depicts a cladogram with numbered and lettered branches. The image includes clades 1, 3, and 7 on one fork of the tree, and clades 2 and 4 on the other. From clade 1 moving up the tree, the first fork is clade 2 which ends in organism group D. From clade 2, clade 5 diverges ending in organism group C. Clade 1 continues up the tree, ending in organism group A. Toward the end of clade 1, clade 4 diverges, ending in organism group B. On the remaining branch of the tree, moving upward from clade 1, clade 3 diverges, ending in organism group E. From clade 3, clade 6 diverges ending in organism group F. Clade 7 diverges from the main branch, ending in organism group G, and the main branch ends in organism group H.

B and E
C and F
A and C
D and H

Based on the cladogram provided, the pair of organisms that are likely to share the most similarities with each other are A and C. This is because they both belong to the same clade (clade 1) and are more closely related than the other pairs mentioned.
