Hi tapasgupta , "increase up to" can be hard.
It may help to think about this sentence in Quant terms.
• exact: increased from 1 million [exact] to 20 million [exact]
• inexact range: increased from 1 million [exact] up to an upper limit of 20 million
[inexact: final number could be 2, 11, or 19.2 million; can't be greater than 20 million]
But how can we have a possible range for a completed and single event?
We cannot. We know the final count. That number is not a probability.
In other cases, we occasionally use "increased up to."
See my example about prices of item XYZ below.
Split #1: Subject/verb agreement
• The subject is number
That subject is followed by a very long prepositional phrase,
of patients newly diagnosed with acid-related diseases
• Number is singular. The verb should be has, not have
Options A and B incorrectly use have.
Eliminate A and B.
Split #2: MEANING
"Increase up to" implies a range, a scaling upwards to an upper limit.
Interest rates increased from 3% up to [as high as] 9% in five years.
-- 9% is the upper limit
-- "up to" number X usually means as high as X and no higher
-- the interest rate must have increased in different places or at different times or both—
from 3% to some rate that was higher than 3% but no higher than 9%
You cannot have a probable range of numbers in the past
for a number about which you are certain.
We are certain about the number of patients diagnosed per year in the past and now.
In the 1980s, the number of patients per year diagnosed with ABC was 1 million.
That number is certain. These patients are countable.
Now that number is 20 million. That number is certain. No range of possibility exists: the figure hit 20 million.
By contrast, increased up to nonsensically suggests that the number of patients DID increase from 1 million
to any of many possible not-yet-happened numbers between 1 million and 20 million, inclusive.
"possibly occurred" and "did occur" cannot co-exist simultaneously about the same thing in the past.
Answers D and E illogically suggest that the number of patients diagnosed each year with acid-disease
increased to some number greater than 1 million but no greater than 20 million.
The number did not increase to one of many possible number. The number increased to a certain number: 20 million.
Eliminate D and E
The correct answer is C
tapasgupta , I hope that analysis helps.
* Usage of increase(d) up to
We can talk about semi-discrete prices with "increased up to"
Correct, past tense: Depending on the city in which XYZ was sold, the price of XYZ increased from $10 up to $20 in the last decade.
-- In NYC, the price of XYZ increased from $10 to $20.
-- In New Orleans, the price of XYZ increased from $10 to $15.
That construction is logical.
Correct, speculation or prediction (future):
In five years, the number of patients diagnosed with ABC per year could or will increase from 20 million up to 30 million.
--In five years the number of patients diagnosed with ABC per year could be 21, 24, 29.9, or 30 million.

1. The number of = Has
2. from X to Y = Correct idiomatic usage...
None but option (C) correctly uses the above 2 forms, hence correct Answer must be (C)
