Answer:
D) Queen Victoria's surprise visit to Ireland was a complete success.
Explanation:
Indomitable will refers to an invincible or impossible to defeat determination. As a consequence, the fact that Victoria made a surprise visit to Ireland does not reflect her strong-minded temper. On the other hand, the rest of the statements do reveal Victoria's resolute character. For instance, her eyesight and other health problems were not an obstacle for her to comply with the royal duties.
