Explanation

The word 'algorithm' derives from the Latin rendering 'Algoritmi' of the name of the Baghdad scholar Muhammad ibn Musa al-Khwarizmi. Working in the House of Wisdom around 825 CE, he wrote the foundational treatise on algebra (Kitab al-Jabr) and on Hindu-Arabic numerals. Ibn al-Haytham, Ibn Rushd and Ibn Sina were distinguished in optics, philosophy and medicine respectively. Hence option A is correct.
