– CH3 is activating group due to +I effect and hyperconjugation.
But for – Cl, – I > + R effect.
But for – Cl, – I > + R effect.
∴CH3 is weakly activating and – Cl is weakly deactivating

Explanation:
When an equimolar mixture of toluene and chlorobenzene is treated with a mixture of concentrated sulfuric acid (H2SO4) and concentrated nitric acid (HNO3), the following reactions occur:
1) Nitration of Toluene:
Toluene reacts with the mixture of concentrated H2SO4 and HNO3 to form p-nitrotoluene. This reaction is known as nitration. The reaction occurs through an electrophilic aromatic substitution mechanism. The nitronium ion (NO2+) is generated as an electrophile in the presence of the acid mixture, which attacks the aromatic ring of toluene to give p-nitrotoluene as the major product.
2) Nitration of Chlorobenzene:
Chlorobenzene also reacts with the mixture of concentrated H2SO4 and HNO3 to form p-nitrochlorobenzene. Similar to the nitration of toluene, the nitronium ion (NO2+) is generated as an electrophile and attacks the aromatic ring of chlorobenzene to give p-nitrochlorobenzene as the major product.
Reason for Correct Answer:
Since an equimolar mixture of toluene and chlorobenzene is used, the concentration of both compounds is the same. Therefore, the reactivity of both compounds towards nitration is expected to be similar. As a result, equal amounts of p-nitrotoluene and p-nitrochlorobenzene will be formed. However, the statement "p-nitrotoluene is formed in excess" is incorrect because it implies that p-nitrotoluene is the major product, which is not the case. Hence, option A is the correct answer.
