Saroj has been suffering with osteoporosis from when she was fifty years old.

Correct option is A

The correct substitution of the highlighted words is (a) from osteoporosis since.
Explanation:
The original phrase "suffering with osteoporosis from when" is grammatically incorrect and awkward. It incorrectly uses:
· The preposition "with", which is not standard in this medical expression.
· The phrase "from when", which is wordy and ungrammatical in standard English.
The correct form is:
"suffer from [disease] since [specific point in time]"
So, the improved sentence is:
"Saroj has been suffering from osteoporosis since she was fifty years old." ✔
Grammatical Rule Used:
✔ "Suffer from" is the standard collocation used when referring to illness or disease.
✔ Use "since" with perfect or perfect continuous tenses to refer to the starting point of an action or condition that is still continuing.
Correct Usage Examples:
· He has been suffering from asthma since childhood.
· She suffers from anxiety due to stress.
Why other options are incorrect:
· (b) from osteoporosis from when – grammatically awkward and repetitive with double "from".
· (c) with osteoporosis since – incorrect use of "with" instead of "from" in medical context.
· (d) no improvement required – incorrect, as the original phrase contains two grammatical errors.
�� Grammar Info Booster:
· ✅ Suffer from – correct expression for diseases or conditions.
·    ❌ Suffer with – informal and not used in standard written English.
· ✅ Use "since + point in time" (e.g., since 2010, since she was 50)
· ✅ Use "for + duration" (e.g., for 10 years, for a decade)
