The correct option is D Family
A group of genera having similar characters comprise a family. In biological classification, family is one of the eight major/obligate taxonomic ranks; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks above the rank of genus. In vernacular usage, a family may be named after one of its common members. e.g., Blattidae - The family of common household cockroaches (Blatta is a commonly seen genus of cockroach).
