William lived in Australia at the 1990s.

• A. <!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--> in
• B. <!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--> at

Answer 1

The correct option is B <!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--> at

<!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--> 'In', not 'at' should be used here to talk about a period of time, 1990s.
