Choose the option that best completes the gap(s).It is _____ responsibility to look after parents in old age?

Answer Details

The option that best completes the gap is "their" because it is a possessive pronoun that shows ownership or possession by a plural subject. In this case, "their" shows that the responsibility to look after parents in old age belongs to multiple people. The other options either have incorrect spellings or incorrect punctuation.
