**Identify the sentences where the word _irrational_ is used correctly in both context and grammar:**
Irrational
(i) The CEO blamed the irrational behavior of the employees for the loss the company had suffered.
(ii) India’s first Census was held in 1872, irrational non-synchronously in different parts of the country.
(iii) Indian Council of Medical Research mulled over setting up network centers to curb the irrational use of drugs.

Question

Accepted Answer

**Solution:**

1. In sentence (i), _irrational_ correctly describes the unreasonable or illogical behavior of employees, which fits the meaning of the word.

2. Sentence (ii) uses _irrational_ incorrectly. The phrase 'irrational non-synchronously' is grammatically awkward and the word _irrational_ does not fit the intended meaning related to timing or scheduling.

3. Sentence (iii) uses _irrational_ appropriately to describe the unreasonable or unjustified use of drugs, which is a common collocation.

Therefore, sentences (i) and (iii) use the word _irrational_ correctly both in meaning and grammar.

**Answer:** (d) both (i) and (iii)
