The correct answer is B. 2/11

The word OBSTRUCTION has 11 letters in total, and two of them is the letter T.

The probability of an event is calculated as the number of successful outcomes divided by the total number of possible outcomes.

In this case, there is only two successful outcome (picking the letter T) and 11 possible outcomes (picking any of the 11 letters), so the probability of picking a letter T from the word OBSTRUCTION is 2/11.

So, the correct answer is A. 1/11.
