Toʻgʻri javob: A) a quarter to ten
To solve this test, one is supposed to know the arrangement of numerals and time parts. The minute hand shows nine, the hour hand shows ten. As it is shown in the picture, the exact time is fifteen minutes to ten. As you know, fifteen can be equal to “a quarter”. Here we can replace “fifteen” to “a quarter” and the structure changes to “a quarter to ten”.
