The relationship between closely related species can be studied by their evolutionary tree. The two species are closely related if they have similar characteristics and nucleotide sequence.
Species A has the DNA sequence TAGCTTAGGGACGG whereas species B has the DNA sequence TACCTTAGGGACGG. These two species have identical nucleotide sequence with minor differences. Hence, these two species are closely related with each other.
Thus, the correct answer is option (B).
