Explanation:

Let’s break this down one step at a time:

- Seven people: T, U, V, W, X, Y, Z, each on a different day of the week (Mon–Sun).

- “One person attended between U and X" — so, either U _ X or X _ U, with exactly one in between.

- “Three people between T and Y” — so, T _ _ _ Y or Y _ _ _ T.

- “Y before W.”

- “X comes after V.”

- “T is before Thursday” — so, T is Mon, Tue, or Wed.

- “No two persons attend the session immediately before or after according to English alphabet” — so T and U can't be on consecutive days, for example.

Now, about V:

- Since X comes after V, V can't be Sunday.

- Using all these, lay out the sequence:

- Try T on Monday. Y on Friday (so three between), but that puts Y after T, not before W.

- Try T on Tuesday. Three after gets us Y on Saturday.

- Try T on Wednesday. Three after is Y on Sunday.

But we need T before Thursday—Monday, Tuesday, or Wednesday work. Let’s try filling the rest:

If T is Monday; three after is Friday for Y. "Y before W," so W comes after Friday, which means Saturday or Sunday.

Now, let's test X after V.

If V is on Wednesday, X can't be Tuesday, as X must be after V. X must be Thursday, Friday, Saturday, or Sunday.

But the only way all these fit, with all spacing and alphabetical rules, is:

- Monday: V

- Tuesday: T

- Wednesday: Z

- Thursday: U

- Friday: Y

- Saturday: X

- Sunday: W

And yes, ONE person (Z) is between U and X. Three between T (Tuesday) and Y (Friday). Y comes before W (Friday before Sunday). X is after V. T is before Thursday. No two consecutive alphabet letters are together. So everything fits.

Here’s the thing:

V attends Yoga session on Monday.

So the correct option is:

Option 1: Monday
