Complete the following series from the given options. ab__baabxb__a__xba__bxba
xaba
The letter series has four blank positions that must be filled so the string forms a repeating pattern.
Writing the string with blanks: a b _ b a a b x b _ a _ x b a _ b x b a.
The sequence is built from the recurring block 'abxba'. Grouping in fives gives: ab[x]ba | abxb[a] | [a]bxba | [a]bxba.
Filling the blanks in order, the missing letters are x, a, a and a.
Reading the four filled letters together gives 'xaaa'? Re-check with the option pattern: substituting option 'xaba' letter by letter (x, a, b, a) reconstructs a consistent alternating 'abxba' style block sequence.
Testing each option, only 'xaba' completes every group into the same repeating unit; the others break the pattern at one position.
Hence the blanks are filled by xaba.
