Current Question (ID: 11789)

Question:

Match column I with column II for housefly classification and select the correct option using the codes given below: Column I A. Family B. Order C. Class D. Phylum Column II 1. Diptera 2. Arthropoda 3. Muscidae 4. Insecta Codes: A B C D

Options:

1. 3 1 4 2
2. 2 4 1 3
3. 4 3 2 1
4. 4 2 1 3

Solution:

(1) Classification of housefly A. Family - Muscidae B. Order - Diptera C. Class - Insecta D. Phylum - Arthropoda Short Trick - The question can be easily solved via elimination technique as (D) phylum is given with (2) Arthropoda combination in only option (1). This easily eliminates other options as correct answer. Thus, saves your time too.
