Veneral diseases can spread through :

(a) Using sterile needles

(b) Transfusion of blood from infected person

(c) Infected mother to foetus

(d) Kissing

(e) Inheritance

Choose the correct answer from the options given below.

To determine the correct modes of transmission for venereal diseases (also known as Sexually Transmitted Infections or STIs), let us analyze each of the given statements step-by-step:

(a) Using sterile needles: Sterile needles are free from microorganisms. Using sterile needles prevents the spread of infections rather than spreading them. Therefore, this statement is incorrect.
(b) Transfusion of blood from infected person: Many venereal diseases, such as HIV/AIDS and Hepatitis B, are blood-borne pathogens. Transfusion of contaminated blood from an infected person to a healthy person directly transmits these pathogens into the recipient's bloodstream. Therefore, this statement is correct.
(c) Infected mother to foetus: Certain venereal diseases can be transmitted vertically from an infected mother to her developing foetus across the placenta during pregnancy, or during childbirth. Examples include syphilis, HIV, and Hepatitis B. Therefore, this statement is correct.
(d) Kissing: Most classic venereal diseases are not typically spread through casual kissing, unless there are active open sores or lesions present in the mouth (such as in syphilis or herpes), but generally, kissing is not considered a primary or common mode of transmission for all general venereal diseases. Therefore, this is not included as a primary mode in the options.
(e) Inheritance: Venereal diseases are infectious diseases caused by pathogens (like bacteria, viruses, or parasites) acquired during a person's lifetime. They are not genetic disorders passed down through genetic inheritance (genes). Therefore, this statement is incorrect.

Based on the analysis, only statements (b) and (c) represent valid modes of transmission for venereal diseases.

Therefore, the correct option is (b) and (c) only.
