Which of the Following is Both a Vector and an Arthropod

Question

Which of the following is both a vector and an arthropod?
A) Contaminated drinking glass
B) Virus
C) Worm
D) Flea

Accepted Answer

A flea is a vector, meaning it can transmit diseases, and it is also an arthropod, as it belongs to the phylum Arthropoda. The other choices are not arthropods; a contaminated drinking glass can transmit pathogens but is not an organism, a virus is not an arthropod (or any other type of organism), and a worm is not an arthropod, although some types of worms can be vectors.
