(a) 3 is Answer , 
token1= DO10I ,

token2= '='

token3=1.25

Within the statement field, blanks were generally ignored, allowing the programmer to omit space between tokens for brevity, or include spaces within identifiers for clarity (for example, AVG OF X was a valid identifier, and equivalent to AVGOFX).

This is a fortran statement and in fortran blanks in fixed-format are ignored hence, in fortran this statement is considered as an instance of the identifier. So number of tokens will be 3 (DO5I, =,1.25).

If statement was like DO 5 I = 1,25 then it would have been considered as a DO statement.
