Which of the following statement is true? a. Two adjacent angles can be complementary
b. Two adjacent angles cannot be supplementary
c. An acute angle cannot be adjacent to an obtuse angles
d. Two right angles cannot be adjacent angles

This is another way of saying two angles next to each other add to 90 degrees. In other words, two angles touching each other forming a corner.

Two adjacent angles can be supplementary, so choice B is false.

An acute angle is always adjacent to an obtuse angle, so choice C is false.

Two right angles can be adjacent, and they would form a straight (180 degree) angle, so that's why choice D is false.
