Select the most appropriate option to fill in the blank.

Though I am tall, I feel inferior ______ others.

to

The correct option to fill in the blank is to.

The sentence is about the speaker feeling inferior to others, even though they are tall. The preposition "to" is used to indicate a comparison between two things. In this case, the speaker is comparing themselves to others, and they feel that they are inferior.

The other options are not as appropriate.

• Than is also used to indicate a comparison between two things, but it is more commonly used for comparisons of quantity or degree. In this case, the speaker is not comparing themselves to others in terms of quantity or degree, they are simply comparing themselves to others in general.
• Upon is used to indicate a position above something or someone. It does not make sense to use this preposition in the context of the sentence because the speaker is not physically above others, they simply feel inferior to them.
• From is used to indicate a direction away from something or someone. It does not make sense to use this preposition in the context of the sentence because the speaker is not moving away from others, they simply feel inferior to them.
