The correct answer is: A. Unbiased
An unbiased person is someone who does not have a particular opinion or preference about something. They are fair and objective in their judgment.
A non-aligned person is someone who does not belong to any particular group or organization. They are independent and do not take sides in any conflict.
An undecided person is someone who has not yet made up their mind about something. They are still considering all the options and have not yet decided which one they prefer.
An indifferent person is someone who does not care about something. They are not interested in it and do not have any strong feelings about it.
In this case, the correct answer is “unbiased” because it is the only option that describes someone who does not have a particular opinion or preference about something. The other options all describe someone who has a particular opinion or preference, or who does not have an opinion or preference yet.
