Find the part of the given sentence that has an error in it. If there is no error, choose ‘No error’.

The joining and eventual separation of Bentley and Rolls-Royce / following a series of mergers and acquisitions, to begin with / the 1931 purchase by Rolls-Royce of Bentley, then in receivership. / No Error

The error lies in option (b).

• Explanation: The phrase “following a series of mergers and acquisitions, to begin with” is structurally faulty because it creates a dangling/unfinished construction and does not link properly with a finite verb for the main subject.
• The sentence needs a clear main verb after the subject “The joining and eventual separation …”. The given segment in (b) interrupts the structure and makes the sentence grammatically incorrect.
• Thus, the error is the faulty participial/connector construction in part (b).

Grammatical rule (English):

• Every sentence must have a subject and a finite verb. Also, participial phrases must logically attach to the correct subject without creating a dangling structure.

व्याकरण नियम (Hindi):

• हर वाक्य में कर्ता और मुख्य क्रिया (finite verb) होना आवश्यक है।
• Participle phrases (following...) को सही subject से जोड़ना चाहिए, नहीं तो dangling structure बनता है।

So the correct answer is (b)
