Answer 2

Answer:

she ________ information to the rival company for a year now

• Given options are mentioned below

1. a. has been leaking
2. b. had been leaking
3. c. was leaking
4. d. leaked

• Right option is b. Had been leaking.

• So the complete sentence is : She had been leaking information to the rival company for a year.

• The above sentence is an example of Past Perfect Continuous Tense .

• Structure : Subject + auxiliary verb - had been + main verb + ing + object / complement ( Since = point of time / For = period of time )

• Example : He had been cheating people for two years.

• Although if we write 'has been leaking' to fill the blank space then it will also be right .

• So both 'had been leaking' and 'has been liking' are correct for the blank space.

• And 'since' and 'for' are restricted for Present, future and Past Perfect Continuous Tense.
