When you want to view specific rows, you need to use the WHERE clause along with a condition.

正確答案是:B: `select id from t1 where id=10;`

專業(yè)分析如下:

1. **選項A: `select id from t1 id=10;`**
- 這個查詢語句是錯誤的。它缺少關鍵字`where`來指定條件。

2. **選項B: `select id from t1 where id=10;`**
- 這個查詢語句是正確的。它使用了`where`關鍵字來指定條件,表示從表`t1`中選擇`id`等于10的行。

3. **選項C: `select id from t1 id 10;`**
- 這個查詢語句是錯誤的。它缺少`where`關鍵字,并且語法不正確。

4. **選項D: `select id from t1 where id 10;`**
- 這個查詢語句是錯誤的。它缺少等號`=`來指定條件。

綜上所述,選項B是正確的查詢語句。
