EnglishSpotting Errors
- ANew types of electrical circuits
- Bhas been developed
- Cby our engineers.
- DNo error
Explanation
The error is in part (b), 'has been developed'. The subject of the clause is 'New types of electrical circuits', which is plural because of 'types'. A plural subject requires a plural verb, so 'has' must be replaced with 'have'. The correct verb phrase is therefore 'have been developed', agreeing with the plural subject. Option (B) marks the error.
