Correct Answer: credit

Solution : The correct option is the fourth option.

Credit: This option fits well in the context, as giving credit to someone means acknowledging or attributing the success or achievement to that person. So, "Akshay always gives credit to Johana for his success" implies that Akshay acknowledges Johana's contribution to his success.

The meanings of the other options are as follows:

• Blame: It means holding someone responsible for something negative or undesirable.
• Chance: It refers to an opportunity or possibility for something to happen.
• Opportunity: An opportunity is a favourable time or occasion for action.

Therefore, the complete sentence is: Akshay always gives credit to Johana for his success .
