Choose the correct answer from the options given below: 
 

• A. A-II, B-I, C-IV, D-III
• B. A-II, B-IV, C-I, D-III
• C. A-II, C-III, B-I, D-IV
• D. A-II, B-I, C-III, D-IV

Hint:

Algal Toxin Pairs:
PSP = Alexandrium
DSP = Prorocentrum Dinophysis
NSP = Gymnodinium (Karenia)
ASP = Nitzschia (Pseudo-nitzschia).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Phycology and harmful algal bloom (HAB) syndromes with their causative marine microalgal genera.

Step 2: Detailed Explanation:
Matching shellfish poisoning syndromes in List I with microalgae in List II:
- A. PSP (Paralytic Shellfish Poisoning): Caused by saxitoxin-producing toxic dinoflagellates of Genus II. {Alexandrium (and Gymnodinium catenatum).
- B. DSP (Diarrhetic Shellfish Poisoning): Caused by okadaic acid-producing dinoflagellates of Genus I. {Prorocentrum (and Dinophysis).
- C. NSP (Neurotoxic Shellfish Poisoning): Caused by brevetoxins from unarmoured dinoflagellates of Genus IV. {Gymnodinium (Karenia brevis).
- D. ASP (Amnesic Shellfish Poisoning): Caused by domoic acid from pennate diatoms of Genus III. {Nitzschia (Pseudo-nitzschia).
Matching sequence: A-II, B-I, C-IV, D-III.

Step 3: Final Answer:
Hence, the correct matching is A-II, B-I, C-IV, D-III, matching option (A).
