Based on the diagram, vector A shows a mosquito while vector B shows a housefly. 

Based on the options, all of the diseases are caused by microorganisms except for goiter, which caused by iodine deficiency. 

However, there are only three diseases that involve vectors, which are malaria, cholera and dengue.

Malaria is a protozoan-caused disease, which carries by a vector known as marsh mosquito (Anopheles). 

Cholera is a bacteria-caused disease, which carries by a vector known as housefly. 

Dengue is a virus-caused disease, which carries by a vector known as Aedes mosquito. 

Tuberculosis on the other hand is an airborne-disease, spreads through bacteria. 

There is no insect vector involves in spreading tuberculosis. 

Therefore, the correct pair is vector A (mosquito) caused Malaria while vector B (housefly) caused cholera. 

Berdasarkan rajah, vektor A menunjukkan seekor nyamuk manakala vektor B menunjukkan seekor lalat.

Berdasarkan pilihan, semua penyakit disebabkan oleh mikroorganisma kecuali goiter, yang disebabkan oleh kekurangan iodin.

Walau bagaimanapun, terdapat hanya tiga penyakit yang melibatkan vektor, iaitu malaria, taun dan denggi.

Malaria adalah penyakit yang disebabkan oleh protozoa, yang dibawa oleh vektor yang dikenali sebagai nyamuk tiruk (Anopheles).

Taun adalah penyakit yang disebabkan oleh bakteria, yang dibawa oleh vektor yang dikenali sebagai lalat. 

Denggi adalah penyakit yang disebabkan oleh virus, yang dibawa oleh vektor yang dikenali sebagai nyamuk Aedes.

Sebaliknya, tuberkulosis adalah penyakit di udara, merebak melalui bakteria.

Tiada vektor serangga yang melibatkan penyebaran tuberkulosis.

Oleh itu, padanan yang betul adalah vektor A (nyamuk) yang menyebabkan Malaria manakala vektor B (lalat) menyebabkan taun. 

Based on the diagram, vector A shows a mosquito while vector B shows a housefly. 

Based on the options, all of the diseases are caused by microorganisms except for goiter, which caused by iodine deficiency.

Therefore, the correct pair is vector A (mosquito) caused Malaria while vector B (housefly) caused cholera.
