It's option B as we need to warmup properly before any strength training session as body temperature plays an important role with the outside temperature. So for at least 10 minutes warmup with body movements, very light dynamic stretching and then warmup with little weights especially the part of the body you are going to train.This way you stay safe and flexible from not getting injured.

For many 11th-grade students, Accountancy becomes one of the most challenging subjects. The difficulties they face usually fall into three main areas.

First, there are time constraints. While solving questions in exams, students often take too long to balance a single account or prepare a statement, which leaves little time for the rest of the paper. This happens mainly because of insufficient practice in a time-bound manner.

Second, many students struggle with understanding the questions. Since Accounts is concept-based, a weak foundation in journal entries, ledgers, and trial balances makes it difficult to approach higher-level problems. Even when they try, confusion about formats and steps leads to mistakes.

Third, there is the fear factor. The lengthy paper, combined with exam pressure, often makes students nervous. Even well-prepared students sometimes panic, forget basic rules, or make silly calculation errors. This fear further lowers their confidence in the subject.

11th graders often face challenges in solving accounting questions due to time constraints, lack of conceptual clarity, and exam anxiety. Tight time limits can cause students to rush, leading to mistakes. Difficulty understanding complex adjustments like depreciation or provisions can further complicate problem-solving. Fear of making errors during exams can cause anxiety, reducing focus and increasing the likelihood of mistakes. Additionally, insufficient practice can make students unsure of their approach. To overcome these, regular practice, mastering key concepts, and improving time management skills are essential for boosting confidence and accuracy during exams.

The assertion is false because metals are not commonly extracted from peroxides; instead, sulphides, oxides, and carbonates are the typical ores. Metal sulphides and carbonates are first converted to oxides, not peroxides, before reduction. Roasting converts sulphides to oxides, and calcination converts carbonates to oxides. These oxides are then reduced using suitable reducing agents like carbon or electrolysis. Hence, the reason is also false, making both the assertion and reason incorrect.
