Official Solution
Correct Option: (1)
A) Morphine — IV) Pain killer: Correct. Morphine is a well-known opioid analgesic (pain reliever). B) Cannabinoids — I) Cardio vascular system: Correct. Cannabinoids like THC can affect the cardiovascular system, causing increased heart rate and blood pressure. C) Cocaine — V) Dopamine: Correct. Cocaine primarily affects the central nervous system by increasing dopamine levels. D) Benzodiazepines — II) Tranquilizers: Correct. Benzodiazepines are sedative drugs used as tranquilizers for anxiety and sleep disorders.

Correct Option: (2)
Step 1: Match each substance with its primary function or effect. \begin{itemize} \item A) Barbiturates: These are central nervous system (CNS) depressants that produce a wide range of effects, from mild sedation to general anesthesia. They are primarily used as sedatives and hypnotics. \item Therefore, A matches with III. Sedatives. \item B) Amphetamines: These are powerful CNS stimulants. They increase alertness, reduce fatigue, and can cause insomnia (sleeplessness). \item Therefore, B matches with I. Cause sleeplessness. \item C) Benzodiazepines: These are a class of psychoactive drugs that are primarily used to treat anxiety, insomnia, and seizures. They are known for their tranquilizing (anxiolytic) effects. \item Therefore, C matches with IV. Tranquilizers. \item D) Cannabinoids: These compounds, found in cannabis, interact with the endocannabinoid system. While they have various effects, high doses and chronic use can have effects on the cardiovascular system (e.g., increased heart rate, changes in blood pressure). The other options (sleeplessness, tranquilizers, sedatives, sterility) are less direct primary effects than cardiovascular system effects or are associated with other drug categories more strongly. Sterility is not a primary or direct effect linked to cannabinoids in the given context. \item Therefore, D matches with II. Cardio vascular system.
\end{itemize} Step 2: Combine the matches.

\begin{itemize} \item Option (1) A-III, B-IV, C-V, D-II (Incorrect, B, C, and V are wrong) \item Option (2) A-III, B-I, C-IV, D-II (Matches our derived combinations) \item Option (3) A-II, B-III, C-I, D-IV (Incorrect, A, B, C, and D are wrong) \item Option (4) A-V, B-II, C-III, D-IV (Incorrect, A, B, C, and D are wrong)
\end{itemize} The final answer is .
