Which of the following methods of designation of crossing is mostly used in India ? A. center line method B. right angle method C. isosceles angle method D. none of the above

The correct answer is: A. center line method

The center line method is the most common method of designation of crossing in India. It is a simple and effective method that uses a single line to indicate the center of the road. This method is easy to understand and follow, and it is effective in preventing accidents.

The right angle method is another method of designation of crossing, but it is not as common as the center line method. The right angle method uses two lines to indicate the center of the road, and these lines intersect at a right angle. This method is more difficult to understand and follow than the center line method, and it is not as effective in preventing accidents.

The isosceles angle method is a third method of designation of crossing, but it is even less common than the right angle method. The isosceles angle method uses three lines to indicate the center of the road, and these lines form an isosceles triangle. This method is the most difficult to understand and follow, and it is the least effective in preventing accidents.

In conclusion, the center line method is the most common and effective method of designation of crossing in India. The right angle method and the isosceles angle method are less common and less effective methods.
