Select the most appropriate option to fill in the blank.
Radium is a white powder that ______ table salt.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. looks like.
The best choice to complete the blank is "looks like."
The proper form to use when describing an attribute or appearance of something is "looks like."
Since we're comparing radium's appearance to table salt in this instance, using the present tense "looks like" is appropriate.
The other choices don't fit the sentence structure and intended meaning because they either employ the wrong verb tense ("look like," "will look like") or the incorrect form ("looking like").
