खालील कोष्टकात गणितीय चिन्हांची नवी परिभाषा दिली आहे. — | + | ÷ | × | = | > | < --------------------------- A | E | C | D | F | G | B वरील कोष्टकाला अनुसरून खालील पर्यायांपैकी कोणते उत्तर अचूक आहे ते ठरवा. Some mathematical symbols are represented in a new notation by letters as shown in the following table. — | + | ÷ | × | = | > | < --------------------------- A | E | C | D | F | G | B Choose the correct expression from the following alternatives.

a)27G25A7E72C4E16D4
b)33B17E8A24C6E3D4
c)64C4F19E9A9C3E6D2
d)16F4D3A2E8C2E2&check; Correct

Substituting the letters back to their mathematical symbols according to the table and evaluating each option using BODMAS shows that option 4 forms a valid mathematical equation.

2)\u00d7 \u0906\u0923\u093f \u00f7 / \u00d7 and \u00f7
3)- \u0906\u0923\u093f \u00f7 / - and \u00f7
4)\u00f7 \u0906\u0923\u093f + / \u00f7 and +&check; Correct

Substitute the mathematical signs from each option into the given equation following the BODMAS rule until the equation balances to -22.
