Minor changes to options file

[AayushyaVajpayee]

What kind of change does this PR introduce?

2 changes which are minor refactor of the code.

1. Use ok_or_else instead of ok_or. This change prevents the string allocation happening on every method call to only happen when there is an error.
2. SImplify nested if else block check_option_contain method. Also use format! macro to prevent to have only one string allocation instead of 2.
