Final answer:
The correct keyboard shortcut to capitalize text from the cursor to the end of the word is Shift + F3 in programs like Microsoft Word, not the options given in the multiple-choice question.
Step-by-step explanation:
The keyboard shortcut that will convert text from the cursor to the end of the word to uppercase is none of the options mentioned (a. Ctrl + U, b. Ctrl + C, c. Ctrl + A, d. Ctrl + W). In most text editing software, like Microsoft Word, you can use Shift + F3 to capitalize text. Using this shortcut repeatedly will toggle the selected text through different capitalization options, including capitalizing each word, the entire selection, or changing it to lowercase.
The shortcuts mentioned are commonly used for other actions within various programs: Ctrl + U is typically for underlining text, Ctrl + C is for copying, Ctrl + A is for selecting all, and Ctrl + W is usually used to close a window or tab.
