Pick out the part of the sentence which has an error. If there is no error, your answer is no error.
The simplest method (A) of welding two pieces of metal together (B) is known as pressure welding. (C)

Correct option is B

Option (b) contains an error.
· Error: The phrase "of welding two pieces of metal together" is redundant.
· The word "welding" already implies joining together, so the word "together" is unnecessary.
Correct sentence: "The simplest method of welding two pieces of metal is known as pressure welding."
Grammatical rule used:
· Avoid redundancy in prepositional phrases or verb-object combinations.
Explanation in Hindi: “Welding” शब्द का अर्थ ही होता है जोड़ना, इसलिए “together” लगाना अनावश्यक और व्याकरणिक रूप से गलत है।
Example:
Incorrect: He joined the two wires together.
Correct: He joined the two wires.
