he Factors influencing for the selection of horizontal Alignment area.Physical and Geophysical conditions.b.Nonec.Geophysical conditions.d.Physical controls.

It seems like you're asking about the factors that influence the selection of horizontal alignment. Here are the factors:

1. Physical and Geophysical Conditions: These refer to the natural conditions of the area where the alignment is to be done. This includes the topography, geology, and soil conditions of the area. For example, a flat and stable area would be more suitable for horizontal alignment than a hilly and unstable area.

2. None: This option suggests that there are no factors influencing the selection of horizontal alignment, which is not accurate. There are always factors to consider in engineering projects.

3. Geophysical Conditions: This is similar to the first point, but focuses more on the geological aspects. This includes the type of rock, the presence of groundwater, and the likelihood of seismic activity.

4. Physical Controls: These are the physical constraints that might affect the alignment. This could include existing structures, property boundaries, and other physical features that need to be worked around.

In conclusion, the selection of horizontal alignment is influenced by a combination of physical and geophysical conditions, as well as any physical controls present in the area.
