Step 1: What the question asks.
Four statements about teamwork are given. We choose which ones describe the components of success.
Step 2: Look for the wrong statement first.
Statement (C) says members do not respect each other. No successful team works like this. So (C) is out, and options 2 and 4 are removed.
Step 3: Look at the remaining options.
Options 1 and 3 remain. The difference is statement (A).
Step 4: Examine (A) closely.
It says teams follow the steps of their own. In teamwork the steps are decided together, so the team moves in one direction. Each person following own steps leads to confusion. So (A) is not correct, and option 3 is removed.
Step 5: Confirm (B) and (D).
Sharing ideas and taking part in finishing the project are basic team actions. Both are right.
Step 6: Result.
Option 1 contains exactly (B) and (D).
Final Answer:
The right components are (B) and (D), option 1.
\[ \boxed{1} \]
