Match the following :

Inventor	Invention
i Charles Babbage	a. Punched Cards
ii. Herman Hollerith	b. Difference Engine
iii. Blaise Pascal	c. Calculator for multiplication.
iv. Baron Gottfried	d. Mechanical adding machine

Choose the most appropriate option from below :

Answer: A

The correct matching is i-b, ii-a, iii-d, iv-c.

Charles Babbage designed the Difference Engine (b), and later the Analytical Engine.
Herman Hollerith built a tabulating machine that read punched cards (a), first used for the 1890 United States census.
Blaise Pascal built the Pascaline in 1642, a mechanical adding machine (d).
Gottfried Wilhelm Leibniz, the 'Baron Gottfried' of the question, built the stepped reckoner, a calculator that could also multiply (c).

Options pairing Hollerith with anything other than punched cards, or Pascal with multiplication, swap these inventions.
