Final answer:
In Microsoft Excel, numerical, date, and time values are automatically right-aligned, while text data is left-aligned. Thus, the answer to the question is A) Text, which is not automatically right-aligned by Excel.
Step-by-step explanation:
When working with Microsoft Excel, different data types are aligned in cells according to conventions that are designed to make the data easier to read and to understand. By default, numeric, date, and time values are right-aligned, which makes it easier to compare figures in a column since the units and decimals will align. On the other hand, text data is generally left-aligned. This is based on common reading habits, where text is read from left to right, and aligning text to the left makes it easier to follow.
Therefore, the data type that is not automatically right-aligned by Excel is A) Text.
