Identify the problems of rural settlements in developing countries carefully:

(A) Most house designs are typically deficient in proper ventilation
(B) Water borne diseases tend to be a common problem
(C) Adequate supply of potable water to rural settlements
(D) Shortage of toilet and garbage disposal facilities

Choose the correct answer from the options given below:

(A), (B) and (D) only

The correct answer is Option (1) → (A), (B) and (D) only

Problems of rural settlements in developing countries typically include:

• (A) Poor housing design: Many rural homes lack proper ventilation, which affects health and living comfort.

• (B) Water-borne diseases: Due to poor sanitation and unclean water sources, diseases like cholera and diarrhea are common.

• (D) Inadequate sanitation: There's often a shortage of toilet and garbage disposal facilities, contributing to poor hygiene.

Why not (C)?

• (C) Adequate supply of potable water is not a problem—lack of potable water would be. Since the statement says “adequate supply,” it implies a solution, not a problem.
