Concept:
Conflicts arise when individuals face competing motives, goals, or choices.
Step 1:
Approach-approach conflict occurs when a person must choose between two desirable alternatives.
\[
A \text{ is correct}
\]
Step 2:
Avoidance-avoidance conflict happens when a person must choose between two unpleasant alternatives.
\[
B \text{ is correct}
\]
Step 3:
Approach-avoidance conflict occurs when the same goal has both positive and negative aspects.
\[
C \text{ is correct}
\]
Step 4:
“Adversity opportunity conflict” is not a recognized psychological conflict category.
\[
D \text{ is incorrect}
\]
Step 5:
Choosing between two lesser evils describes avoidance-avoidance conflict, not approach-approach conflict.
\[
E \text{ is incorrect}
\]
Step 6:
Thus, the correct combination is:
\[
A,\ B,\ C \text{ Only}
\]
\[
\boxed{\text{(2) A, B and C Only}}
\]
