conclusion - Computers manufacture

sukrant26

All computers manufactured after 1998 have a minimum processing speed of 400 MHz. My computer has a processing speed of 399 MHz.

Which of the following can definitely NOT be concluded from the above statements?
I) My computer was definitely manufactured after 1998.
II) My computer may have been manufactured in 1998.
III) If it had been manufactured a year later, my computer would have had a faster processing speed.

(A) I only

(B) II only

(3) III only

(D) I and III only

(E) II and III only

Can we "definitely not conclude" III. I thought we can definitely not conclude only I. And III is probably true.

Please explain

i think the answer is d. we cannot conclude 1 and 3.
III) If it had been manufactured a year later, my computer would have had a faster processing speed.
from the statement, we do not know which year the person's computer was manufactured. the statement 3 is true only if the comp was manufactured in 98. what if it was manufctrd in 87?
what is the answer?
