Okay, let's analyze why "bright" is the best answer, and why the others aren't as suitable.

• Understanding the Sentence: The sentence sets up a contrast: poor performance versus selection chances. The word that fills the blank needs to make sense in light of this contrast.

• Why "bright" is the best choice: "Bright" suggests that despite the poor performances, there's a good possibility of K.L. Rahul being selected. This implies that other factors (such as past performance, captain's preference, or lack of other options) are overriding the current poor form.

• Why the other options are less suitable:

  • (A) slim: "Slim" means unlikely. This contradicts the implied meaning of the sentence, which suggests selection is still possible despite poor performance.
  • (C) obvious: "Obvious" means easily understood or clear. If Rahul's performances were poor, his selection wouldn't be obvious.
  • (D) uncertain: "Uncertain" is a possible answer, but not as strong as "bright". The sentence suggests that there is some reason to believe that KL Rahul may get selected.

Therefore, "bright" is the most logical and appropriate word to fill the blank, highlighting the unexpected possibility of selection despite poor performance.
