B. neither has electron pair available for donation nor can accommodate electron since all shells of N are fully occupied
C. can act as Lewise acid and base
D. none of these

Explanation

To determine why the compound \((CH_3)_4N^+\) is neither an electrophile nor a nucleophile, we can analyze its structure and electronic configuration step by step.

### Step 1: Identify the Structure of the Compound
The compound \((CH_3)_4N^+\) consists of a nitrogen atom bonded to four methyl groups (CH₃). This means that nitrogen is surrounded by four carbon atoms.

**Hint:** Look at the number of substituents attached to the central atom (nitrogen in this case).

### Step 2: Determine the Hybridization and Bonding of Nitrogen
In \((CH_3)_4N^+\), nitrogen forms four sigma bonds with the four methyl groups. This means nitrogen is sp³ hybridized.

**Hint:** Recall that sp³ hybridization involves four bonds, leading to a tetrahedral geometry.

### Step 3: Analyze the Charge on the Nitrogen Atom
The nitrogen atom in this compound has four bonds and carries a positive charge (\(N^+\)). This indicates that nitrogen has used all its valence electrons to form bonds, resulting in a complete octet.

**Hint:** Remember that a positive charge indicates a deficiency of electrons compared to a neutral atom.

### Step 4: Evaluate Nucleophilicity
A nucleophile is typically characterized by the presence of a lone pair of electrons or a negative charge, allowing it to donate electrons. In \((CH_3)_4N^+\), nitrogen does not have a lone pair because all its valence electrons are involved in bonding. Therefore, it cannot act as a nucleophile.

**Hint:** Nucleophiles need either a lone pair or a negative charge to donate electrons.

### Step 5: Evaluate Electrophilicity
An electrophile is an electron-deficient species that can accept electrons. For a species to act as an electrophile, it usually has an incomplete octet or a positive charge. However, in this case, nitrogen has a complete octet (8 electrons from 4 bonds), meaning it is not electron-deficient. Therefore, it cannot act as an electrophile.

**Hint:** Electrophiles often have incomplete octets or are positively charged but need to be electron-deficient.

### Conclusion
Since \((CH_3)_4N^+\) has no lone pairs and its octet is complete, it is neither a nucleophile nor an electrophile.

### Final Answer
\((CH_3)_4N^+\) is neither an electrophile nor a nucleophile because it has no lone pair for donation and its octet is fully occupied.
