We are given the following reaction and tasked with identifying the product (A):

The reaction involves a certain reagent (which is likely a halogen or a reagent like Br2 or Cl2), and the compound reacts with it under specific conditions (such as light or heat). This suggests that the reaction involves the formation of a product through a substitution or addition mechanism.
Based on the reaction shown, the likely outcome of the reaction is the formation of a product where a substitution has occurred (for example, an alkyl halide or an alkene depending on the type of reagent and reaction conditions).
The product formed in this reaction is:

The product (A) of the reaction is shown in the image above.
Given below are two statements:
Statement I: Dimethyl ether is completely soluble in water. However, diethyl ether is soluble in water to a very small extent.
Statement II: Sodium metal can be used to dry diethyl ether and not ethyl alcohol.
In the light of the given statements, choose the correct answer from the options given below:
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
