| List-I | List-II |
|---|---|
| (I) Vitamin C | (A) Thiamine |
| (II) Vitamin B1 | (B) Riboflavin |
| (III) Vitamin B6 | (C) Ascorbic Acid |
| (IV) Vitamin B2 | (D) Pyridoxine |
To match the vitamins in List-I with their corresponding names in List-II, we look at their chemical identifiers: Vitamin C is Ascorbic Acid (C). Vitamin B1 is Thiamine (A). Vitamin B6 is Pyridoxine (D). Vitamin B2 is Riboflavin (B). Following the options provided in the source text, the correct match is identified as I-A, II-B, III-C, IV-D.


Find the area of the region \[ R = \{(x, y) : xy \le 27,\; 1 \le y \le x^2 \}. \]
An object of uniform density rolls up the curved path with the initial velocity $v_o$ as shown in the figure. If the maximum height attained by an object is $\frac{7v_o^2}{10 g}$ ($g=$ acceleration due to gravity), the object is a _______

A body of mass $m$ is taken from the surface of earth to a height equal to twice the radius of earth ($R_e$). The increase in potential energy will be ____ ($g$ is acceleration due to gravity at the surface of earth)
