Answer : (1) The correct option is, (A) increases
(2) The correct option is, (C) Decreases
Explanation :
Gravitational force : It is defined as the gravitational force is directly proportional to the product of the masses of the two object and an inversely proportional to the square of the distance between the two object.

where,
F = gravitational force or gravity
M and m = mass of two object
r = distance between the two object
G = gravitational constant
When the mass of an object increases then the gravitational force or gravity is increases because gravitational force is directly proportional to the mass of an object.
When the distance between the two object increases then the gravitational force or gravity is decreases because gravitational force is inversely proportional to the distance between the two object.
Hence, (1) As mass increases, gravity increases. (2) As distance increases, gravity decreases.
