Fill in the blank with the correct preposition.
Shyam is confident __________his failure.

about

The correct preposition to fill in the blank is "about":OPTION 2

• "For" implies confidence in anticipation of failure, meaning he trusts his ability to handle it when it happens.
• "Towards" suggests a feeling or attitude directed towards the concept of failure, which isn't specific enough.
• "Of" can imply possession or belonging, which makes little sense in this context.
• "About" accurately conveys that Shyam is aware of his failure and has feelings regarding it, whether those feelings are acceptance, resilience, or even a desire to learn from it.

Therefore,"Shyam is confident about his failure" best expresses the intended meaning.
