Option (B).

Explanation:

Mixture may be defined as the solution obtained by mixing of two or more substances together. Two different types of mixture are homogeneous mixture and heterogeneous mixture.

Homogeneous mixture may be defined as the mixture that has uniform composition throughout the mixture and cannot be separated easily by physical shaking process. Heterogeneous mixture are the mixtures that has different composition throughout the mixture and can be separated by simple shaking.

Thus, the correct answer is option (B).

Some possible answers are: unrestricted growth, unlimited use of cars and building or extensive road networks. Unrestricted growth in a city means that there is often insufficient housing near the city centre, and people move outwards to find affordable housing. The use of cars along with extensive road networks has also provided people the ability to commute longer distances to work, resulting in more outlying residential areas. I would add lack of housing planning as another factor leading to housing prices near the city centre being unaffordable for most middle-class families.
