To determine the combination that increases the stability of an object, let's analyze the principles of stability in physical objects. Stability in structures or objects is influenced mainly by two factors: the width of their base and the position of their center of gravity (C.G).

1. Wide Base: A wider base provides a larger area of support, which helps in stabilizing the object. Objects with wide bases are less likely to tip over compared to those with narrow bases.

2. Center of Gravity (C.G): The center of gravity is the point where the total weight of the object is considered to be concentrated. Lowering the center of gravity increases stability because it reduces the likelihood of tipping. An object with a low center of gravity is more stable than one with a high center of gravity.

Now, let's evaluate each option:

Option A: Wide base and low C.G
- A wide base increases the stability.
- A low center of gravity also increases the stability.
- Combining both factors results in maximum stability.

Option B: Narrow base and low C.G
- A narrow base decreases the stability.
- A low center of gravity increases the stability.
- Combining these factors results in moderate stability but not as optimal since the narrow base reduces overall stability.

Option C: Narrow base and high C.G
- A narrow base decreases the stability.
- A high center of gravity further decreases the stability.
- Combining these factors results in very low stability.

Option D: Wide base and high C.G
- A wide base increases the stability.
- A high center of gravity decreases the stability.
- Combining these factors results in moderate stability but not the optimal choice given the high center of gravity.

Option E: Wide base and C.G one third of the way up from the base
- A wide base increases the stability.
- A center of gravity positioned one third of the way up from the base is relatively low but not as low as possible.
- This combination is stable, but not as optimal as having the lowest center of gravity.

Considering all the above points, the combination that provides the highest stability is:

Option A: Wide base and low C.G

Therefore, the answer is Option A.
