Concept:
At an uncontrolled four-legged intersection, vehicle movements create three types of conflict points:
For a two-lane, two-way intersection:
\[ \boxed{ \begin{aligned} \text{Crossing conflicts} &= 16 \\ \text{Merging conflicts} &= 8 \\ \text{Diverging conflicts} &= 8 \end{aligned} } \]
Thus, the total number of conflict points is:
\[ 16 + 8 + 8 = 32. \]
The question asks only for the major conflict points, which are the crossing conflicts.
Step 1: Identify the major conflict type.
Major conflicts correspond to crossing movements.
\[ \boxed{\text{Major conflict points} = 16} \]
Step 2: Select the correct option.
Answer:
\[ \boxed{(C)\ 16} \]
