Ninja Strategy•Two-Step Confirmation

Confirm the matches for the two most common bacterial shapes, Spherical (Cocci) and Rod (Bacilli), to instantly find the only correct option.

Step 1: Identify the Matching Pairs✦ Active

The question requires matching the descriptive shape of bacteria in List-I with their correct scientific name in List-II. We need to recall the standard terminology for bacterial morphology.

Step 2: Perform the Matching○ Expand

Let's match each item from List-I to List-II: - A. Spherical bacteria are known as Cocci. So, A matches with II. - B. Rod-shaped bacteria are known as Bacilli. So, B matches with IV. - C. Comma-shaped bacteria are known as Vibrio. So, C matches with I. - D. Spirillum (spiral-shaped) bacteria are known as Spirilla. So, D matches with III.

💡 Teacher's Secret Hint

The singular form is often used in the description (e.g., Spirillum), while the plural form is used for the group name (e.g., Spirilla). Don't get confused by this.
