Question

Which one the following is the correct matching of three items and their grouping category?

• A. $\begin{array}{cc}\text{Items}& \text{Group}\\ \text{Ilium,ischium,pubis girdle}& \text{Coxal bones of pelvic}\end{array}$
• B. $\begin{array}{cc}\text{Items}& \text{Group}\\ \text{Actin, myosin, rhodopsin}& \text{Muscle protein}\end{array}$
• C. $\begin{array}{cc}\text{Items}& \text{Group}\\ \text{Cytosine, uracil, thiamine}& \text{Pyrimidines}\end{array}$
• D. $\begin{array}{cc}\text{Items}& \text{Group}\\ \text{Malleus, incus, cochlea}& \text{Ear ossicles}\end{array}$

Answer 1

The correct option is A $\begin{array}{cc}\text{Items}& \text{Group}\\ \text{Ilium,ischium,pubis girdle}& \text{Coxal bones of pelvic}\end{array}$

The pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones – ilium, ischium, and pubis.
Muscle proteins are actin and myosin.
Pyrimidines are thymine, cytosine and uracil. (Thiamine is a vitamin).
Ear ossicles are malleus, incus, and stapes.
